Natural ultramarine pigment in powdered form

Synthetic ultramarine pigment is chemically identical to natural ultramarine

A pigment is a material that changes the color of reflected or transmitted light as the result of wavelength-selective absorption. This physical process differs from fluorescence, phosphorescence, and other forms of luminescence, in which a material emits light.

Many materials selectively absorb certain wavelengths of light. Materials that humans have chosen and developed for use as pigments usually have special properties that make them ideal for coloring other materials. A pigment must have a high tinting strength relative to the materials it colors. It must be stable in solid form at ambient temperatures.

For industrial applications, as well as in the arts, permanence and stability are desirable properties. Pigments that are not permanent are called fugitive. Fugitive pigments fade over time, or with exposure to light, while some eventually blacken.

Pigments are used for coloring paint, ink, plastic, fabric, cosmetics, food and other materials. Most pigments used in manufacturing and the visual arts are dry colorants, usually ground into a fine powder. This powder is added to a vehicle (or binder), a relatively neutral or colorless material that suspends the pigment and gives the paint its adhesion.

The worldwide market for inorganic, organic and special pigments had a total volume of around 7.4 million tons in 2006. Asia has the highest rate on a quantity basis followed by Europe and North America. In 2006, a turnover of 17.6 billion US$ (13 billion euro) was reached mostly in Europe, followed by North America and Asia.^[1] The global demand on pigments was roughly US$ 20.5 billion in 2009, around 1.5-2% up from the previous year. It is predicted to increase in a stable growth rate in the coming years. The worldwide sales are said to increase up to US$ 24.5 billion in 2015, and reach US$ 27.5 billion in 2018.^[2]

A distinction is usually made between a pigment, which is insoluble in the vehicle (resulting in a suspension), and a dye, which either is itself a liquid or is soluble in its vehicle (resulting in a solution). The term biological pigment is used for all colored substances independent of their solubility. A colorant can be both a pigment and a dye depending on the vehicle it is used in. In some cases, a pigment can be manufactured from a dye by precipitating a soluble dye with a metallic salt. The resulting pigment is called a lake pigment.

Physical basis[link]

A wide variety of wavelengths (colors) encounter a pigment. This pigment absorbs red and green light, but reflects blue, creating the color blue.

Pigments appear the colors they are because they selectively reflect and absorb certain wavelengths of visible light. White light is a roughly equal mixture of the entire spectrum of visible light with a wavelength in a range from about 380 or 400 nanometers to about 760 or 780 nm. When this light encounters a pigment, parts of the spectrum are absorbed by the chemical bonds of conjugated systems and other components of the pigment. Some other wavelengths or parts of the spectrum are reflected or scattered. Most pigments are charge-transfer complexes, like transition metal compounds, with broad absorption bands that subtract most of the colors of the incident white light. The new reflected light spectrum creates the appearance of a color. Ultramarine reflects blue light, and absorbs other colors. Pigments, unlike fluorescent or phosphorescent substances, can only subtract wavelengths from the source light, never add new ones.

The appearance of pigments is intimately connected to the color of the source light. Sunlight has a high color temperature, and a fairly uniform spectrum, and is considered a standard for white light. Artificial light sources tend to have great peaks in some parts of their spectrum, and deep valleys in others. Viewed under these conditions, pigments will appear different colors.

Color spaces used to represent colors numerically must specify their light source. Lab color measurements, unless otherwise noted, assume that the measurement was taken under a D65 light source, or "Daylight 6500 K", which is roughly the color temperature of sunlight.

Sunlight encounters Rosco R80 "Primary Blue" pigment. The product of the source spectrum and the reflectance spectrum of the pigment results in the final spectrum, and the appearance of blue.

Other properties of a color, such as its saturation or lightness, may be determined by the other substances that accompany pigments. Binders and fillers added to pure pigment chemicals also have their own reflection and absorption patterns, which can affect the final spectrum. Likewise, in pigment/binder mixtures, individual rays of light may not encounter pigment molecules, and may be reflected as is. These stray rays of source light contribute to the saturation of the color. Pure pigment allows very little white light to escape, producing a highly saturated color. A small quantity of pigment mixed with a lot of white binder, however, will appear desaturated and pale, due to the high quantity of escaping white light.

History[link]

Naturally occurring pigments such as ochres and iron oxides have been used as colorants since prehistoric times. Archaeologists have uncovered evidence that early humans used paint for aesthetic purposes such as body decoration. Pigments and paint grinding equipment believed to be between 350,000 and 400,000 years old have been reported in a cave at Twin Rivers, near Lusaka, Zambia.

Before the Industrial Revolution, the range of color available for art and decorative uses was technically limited. Most of the pigments in use were earth and mineral pigments, or pigments of biological origin. Pigments from unusual sources such as botanical materials, animal waste, insects, and mollusks were harvested and traded over long distances. Some colors were costly or impossible to mix with the range of pigments that were available. Blue and purple came to be associated with royalty because of their expense.

Biological pigments were often difficult to acquire, and the details of their production were kept secret by the manufacturers. Tyrian Purple is a pigment made from the mucus of one of several species of Murex snail. Production of Tyrian Purple for use as a fabric dye began as early as 1200 BCE by the Phoenicians, and was continued by the Greeks and Romans until 1453 CE, with the fall of Constantinople.^[3] The pigment was expensive and complex to produce, and items colored with it became associated with power and wealth. Greek historian Theopompus, writing in the 4th century BCE, reported that "purple for dyes fetched its weight in silver at Colophon [in Asia Minor]."^[4]

Mineral pigments were also traded over long distances. The only way to achieve a deep rich blue was by using a semi-precious stone, lapis lazuli, to produce a pigment known as ultramarine, and the best sources of lapis were remote. Flemish painter Jan Van Eyck, working in the 15th century, did not ordinarily include blue in his paintings. To have one's portrait commissioned and painted with ultramarine blue was considered a great luxury. If a patron wanted blue, they were forced to pay extra. When Van Eyck used lapis, he never blended it with other colors. Instead he applied it in pure form, almost as a decorative glaze.^[5] The prohibitive price of lapis lazuli forced artists to seek less expensive replacement pigments, both mineral (azurite, smalt) and biological (indigo).

Miracle of the Slave by Tintoretto (c. 1548). The son of a master dyer, Tintoretto used Carmine Red Lake pigment, derived from the cochineal insect, to achieve dramatic color effects.

Spain's conquest of a New World empire in the 16th century introduced new pigments and colors to peoples on both sides of the Atlantic. Carmine, a dye and pigment derived from a parasitic insect found in Central and South America, attained great status and value in Europe. Produced from harvested, dried, and crushed cochineal insects, carmine could be, and still is, used in fabric dye, food dye, body paint, or in its solid lake form, almost any kind of paint or cosmetic.

Natives of Peru had been producing cochineal dyes for textiles since at least 700 CE,^[6] but Europeans had never seen the color before. When the Spanish invaded the Aztec empire in what is now Mexico, they were quick to exploit the color for new trade opportunities. Carmine became the region's second most valuable export next to silver. Pigments produced from the cochineal insect gave the Catholic cardinals their vibrant robes and the English "Redcoats" their distinctive uniforms. The true source of the pigment, an insect, was kept secret until the 18th century, when biologists discovered the source.^[7]

While Carmine was popular in Europe, blue remained an exclusive color, associated with wealth and status. The 17th century Dutch master Johannes Vermeer often made lavish use of lapis lazuli, along with Carmine and Indian yellow, in his vibrant paintings.

Development of synthetic pigments[link]

The earliest known pigments were natural minerals. Natural iron oxides give a range of colors and are found in many Paleolithic and Neolithic cave paintings. Two examples include Red Ochre, anhydrous Fe₂O₃, and the hydrated Yellow Ochre (Fe₂O₃^.H₂O).^[8] Charcoal, or carbon black, has also been used as a black pigment since prehistoric times.^[8]

Two of the first synthetic pigments were white lead (basic lead carbonate, (PbCO₃)₂Pb(OH)₂) and blue frit (Egyptian Blue). White lead is made by combining lead with vinegar (acetic acid, CH₃COOH) in the presence of CO₂. Blue frit is calcium copper silicate and was made from glass colored with a copper ore, such as malachite. These pigments were used as early as the second millennium BCE^[9]

The Industrial and Scientific Revolutions brought a huge expansion in the range of synthetic pigments, pigments that are manufactured or refined from naturally occurring materials, available both for manufacturing and artistic expression. Because of the expense of Lapis Lazuli, much effort went into finding a less costly blue pigment.

Prussian Blue was the first modern synthetic pigment, discovered by accident in 1704. By the early 19th century, synthetic and metallic blue pigments had been added to the range of blues, including French ultramarine, a synthetic form of lapis lazuli, and the various forms of Cobalt and Cerulean Blue. In the early 20th century, organic chemistry added Phthalo Blue, a synthetic, organometallic pigment with overwhelming tinting power.

Self Portrait by Paul Cézanne. Working in the late 19th century, Cézanne had a palette of colors that earlier generations of artists could only have dreamed of.

Discoveries in color science created new industries and drove changes in fashion and taste. The discovery in 1856 of mauveine, the first aniline dye, was a forerunner for the development of hundreds of synthetic dyes and pigments like azo and diazo compounds which are the source of wide spectrum of colors. Mauveine was discovered by an 18-year-old chemist named William Henry Perkin, who went on to exploit his discovery in industry and become wealthy. His success attracted a generation of followers, as young scientists went into organic chemistry to pursue riches. Within a few years, chemists had synthesized a substitute for madder in the production of Alizarin Crimson. By the closing decades of the 19th century, textiles, paints, and other commodities in colors such as red, crimson, blue, and purple had become affordable.^[10]

Development of chemical pigments and dyes helped bring new industrial prosperity to Germany and other countries in northern Europe, but it brought dissolution and decline elsewhere. In Spain's former New World empire, the production of cochineal colors employed thousands of low-paid workers. The Spanish monopoly on cochineal production had been worth a fortune until the early 19th century, when the Mexican War of Independence and other market changes disrupted production.^[11] Organic chemistry delivered the final blow for the cochineal color industry. When chemists created inexpensive substitutes for carmine, an industry and a way of life went into steep decline.^[12]

New sources for historic pigments[link]

The Milkmaid by Johannes Vermeer (c. 1658). Vermeer was lavish in his choice of expensive pigments, including Indian Yellow, lapis lazuli, and Carmine, as shown in this vibrant painting.

Before the Industrial Revolution, many pigments were known by the location where they were produced. Pigments based on minerals and clays often bore the name of the city or region where they were mined. Raw Sienna and Burnt Sienna came from Siena, Italy, while Raw Umber and Burnt Umber came from Umbria. These pigments were among the easiest to synthesize, and chemists created modern colors based on the originals that were more consistent than colors mined from the original ore bodies. But the place names remained.

Historically and culturally, many famous natural pigments have been replaced with synthetic pigments, while retaining historic names. In some cases the original color name has shifted in meaning, as a historic name has been applied to a popular modern color. By convention, a contemporary mixture of pigments that replaces a historical pigment is indicated by calling the resulting color a hue, but manufacturers are not always careful in maintaining this distinction. The following examples illustrate the shifting nature of historic pigment names:

Titian used the historic pigment Vermilion to create the reds in the great fresco of Assunta, completed c. 1518.

• Indian Yellow was once produced by collecting the urine of cattle that had been fed only mango leaves^{[citation needed]}. Dutch and Flemish painters of the 17th and 18th centuries favored it for its luminescent qualities, and often used it to represent sunlight^{[citation needed]}. In the novel Girl with a Pearl Earring, Vermeer's patron remarks that Vermeer used "cow piss" to paint his wife.^[13] Since mango leaves are nutritionally inadequate for cattle, the practice of harvesting Indian Yellow was eventually declared to be inhumane^{[citation needed]}. Modern hues of Indian Yellow are made from synthetic pigments.
• Ultramarine, originally the semi-precious stone lapis lazuli, has been replaced by an inexpensive modern synthetic pigment, French Ultramarine, manufactured from aluminium silicate with sulfur impurities. At the same time, Royal Blue, another name once given to tints produced from lapis lazuli, has evolved to signify a much lighter and brighter color, and is usually mixed from Phthalo Blue and titanium dioxide, or from inexpensive synthetic blue dyes. Since synthetic ultramarine is chemically identical with lapis lazuli, the "hue" designation is not used. French Blue, yet another historic name for ultramarine, was adopted by the textile and apparel industry as a color name in the 1990s, and was applied to a shade of blue that has nothing in common with the historic pigment ultramarine.
• Vermilion, a toxic mercury compound favored for its deep red-orange color by old master painters such as Titian, has been replaced in painters' palettes by various modern pigments, including cadmium reds. Although genuine Vermilion paint can still be purchased for fine arts and art conservation applications, few manufacturers make it, because of legal liability issues. Few artists buy it, because it has been superseded by modern pigments that are both less expensive and less toxic, as well as less reactive with other pigments. As a result, genuine Vermilion is almost unavailable. Modern vermilion colors are properly designated as Vermilion Hue to distinguish them from genuine Vermilion.

Manufacturing and industrial standards[link]

Before the development of synthetic pigments, and the refinement of techniques for extracting mineral pigments, batches of color were often inconsistent. With the development of a modern color industry, manufacturers and professionals have cooperated to create international standards for identifying, producing, measuring, and testing colors.

First published in 1905, the Munsell Color System became the foundation for a series of color models, providing objective methods for the measurement of color. The Munsell system describes a color in three dimensions, hue, value (lightness), and chroma (color purity), where chroma is the difference from gray at a given hue and value.

By the middle years of the 20th century, standardized methods for pigment chemistry were available, part of an international movement to create such standards in industry. The International Organization for Standardization (ISO) develops technical standards for the manufacture of pigments and dyes. ISO standards define various industrial and chemical properties, and how to test for them. The principal ISO standards that relate to all pigments are as follows:

• ISO-787 General methods of test for pigments and extenders.
• ISO-8780 Methods of dispersion for assessment of dispersion characteristics.

Other ISO standards pertain to particular classes or categories of pigments, based on their chemical composition, such as ultramarine pigments, titanium dioxide, iron oxide pigments, and so forth.

Many manufacturers of paints, inks, textiles, plastics, and colors have voluntarily adopted the Colour Index International (CII) as a standard for identifying the pigments that they use in manufacturing particular colors. First published in 1925, and now published jointly on the web by the Society of Dyers and Colourists (United Kingdom) and the American Association of Textile Chemists and Colorists (USA), this index is recognized internationally as the authoritative reference on colorants. It encompasses more than 27,000 products under more than 13,000 generic color index names.

In the CII schema, each pigment has a generic index number that identifies it chemically, regardless of proprietary and historic names. For example, Phthalo Blue has been known by a variety of generic and proprietary names since its discovery in the 1930s. In much of Europe, phthalocyanine blue is better known as Helio Blue, or by a proprietary name such as Winsor Blue. An American paint manufacturer, Grumbacher, registered an alternate spelling (Thalo Blue) as a trademark. Colour Index International resolves all these conflicting historic, generic, and proprietary names so that manufacturers and consumers can identify the pigment (or dye) used in a particular color product. In the CII, all Phthalo Blue pigments are designated by a generic color index number as either PB15 or PB16, short for pigment blue 15 and pigment blue 16. (The two forms of Phthalo Blue, PB15 and PB16, reflect slight variations in molecular structure that produce a slightly more greenish or reddish blue.)

Scientific and technical issues[link]

Selection of a pigment for a particular application is determined by cost, and by the physical properties and attributes of the pigment itself. For example, a pigment that is used to color glass must have very high heat stability in order to survive the manufacturing process; but, suspended in the glass vehicle, its resistance to alkali or acidic materials is not an issue. In artistic paint, heat stability is less important, while lightfastness and toxicity are greater concerns.

The following are some of the attributes of pigments that determine their suitability for particular manufacturing processes and applications:

• Lightfastness and sensitivity for damage from ultra violet light
• Heat stability
• Toxicity
• Tinting strength
• Staining
• Dispersion
• Opacity or transparency
• Resistance to alkalis and acids
• Reactions and interactions between pigments

Swatches[link]

Pure pigments reflect light in a very specific way that cannot be precisely duplicated by the discrete light emitters in a computer display. However, by making careful measurements of pigments, close approximations can be made. The Munsell Color System provides a good conceptual explanation of what is missing. Munsell devised a system that provides an objective measure of color in three dimensions: hue, value (or lightness), and chroma. Computer displays in general are unable to show the true chroma of many pigments, but the hue and lightness can be reproduced with relative accuracy. However, when the gamma of a computer display deviates from the reference value, the hue is also systematically biased.

The following approximations assume a display device at gamma 2.2, using the sRGB color space. The further a display device deviates from these standards, the less accurate these swatches will be.^[14] Swatches are based on the average measurements of several lots of single-pigment watercolor paints, converted from Lab color space to sRGB color space for viewing on a computer display. Different brands and lots of the same pigment may vary in color. Furthermore, pigments have inherently complex reflectance spectra that will render their color appearance greatly different depending on the spectrum of the source illumination; a property called metamerism. Averaged measurements of pigment samples will only yield approximations of their true appearance under a specific source of illumination. Computer display systems use a technique called chromatic adaptation transforms^[15] to emulate the correlated color temperature of illumination sources, and cannot perfectly reproduce the intricate spectral combinations originally seen. In many cases the perceived color of a pigment falls outside of the gamut of computer displays and a method called gamut mapping is used to approximate the true appearance. Gamut mapping trades off any one of Lightness, Hue or Saturation accuracy to render the color on screen, depending on the priority chosen in the conversion's ICC rendering intent.

Biological pigments[link]

In biology, a pigment is any colored material of plant or animal cells. Many biological structures, such as skin, eyes, fur and hair contain pigments (such as melanin). Animal skin coloration is often achieved with specialized cells called chromatophores, which in animals such as the octopus and chameleon can be controlled to vary the animal's color. Many conditions affect the levels or nature of pigments in plant, animal, some protista, or fungus cells. For instance, Albinism is a disorder affecting the level of melanin production in animals.

Pigmentation is used in organisms for many biological purposes including Camouflage, Mimicry, Aposematism (warning), Sexual selection and other forms of Signalling, Photosynthesis (in plants), as well as basic physical purposes such as protection from Sunburn.

Pigment color differs from structural color in that it is the same for all viewing angles, whereas structural color is the result of selective reflection or iridescence, usually because of multilayer structures. For example, butterfly wings typically contain structural color, although many butterflies have cells that contain pigment as well.

It has been suggested that Diana Prince be merged into this article or section. (Discuss) Proposed since September 2011.

Wonder Woman is a fictional character, a DC Comics superheroine created by William Moulton Marston. She first appeared in All Star Comics #8 (December 1941). The Wonder Woman title has been published by DC Comics almost continuously except for a brief hiatus in 1986.^[1]

Wonder Woman is a warrior Princess of the Amazons (based on the Amazons of Greek mythology) and was created by Marston, an American, as a "distinctly feminist role model whose mission was to bring the Amazon ideals of love, peace, and sexual equality to a world torn by the hatred of men." ^[2] Known in her homeland as Diana of Themyscira, her powers include superhuman strength, flight (even though the original Wonder Woman did not have this ability), super-speed, super-stamina, and super-agility. She is highly proficient in hand-to-hand combat and in the art of tactical warfare. She also possesses animal-like cunning skills and a natural rapport with animals, which has been presented as an actual ability to communicate with the animal kingdom. She uses her Lasso of Truth, which forces those bound by it to tell the truth, a pair of indestructible bracelets, a tiara which serves as a projectile, and, in some stories, an invisible airplane.

Created during World War II, the character was initially depicted fighting the Axis military forces, as well as an assortment of supervillains. In later decades, some writers maintained the World War II setting, with many of its themes and story arcs, while others updated the series to reflect the present day. Wonder Woman has also regularly appeared in comic books featuring the superhero teams Justice Society (from 1941) and Justice League (from 1960). Arguably the most popular and iconic female superhero in comics, Wonder Woman is also considered a feminist icon.^[2] She was named the 20th greatest comic book character by Empire magazine.^[3] She was ranked sixth in Comics Buyer's Guide's "100 Sexiest Women in Comics" list.^[4]

In addition to the comics, the character has appeared in other media; most notably, the 1975–1979 Wonder Woman TV series starring Lynda Carter, as well as animated series such as the Super Friends and Justice League. Although a number of attempts have been made to adapt the character to live-action film, none has yet emerged from development hell. An animated film was released in 2009, with Keri Russell voicing the title role. In 2011, Adrianne Palicki starred in a failed pilot for a would-be series about the character.

In May 2011, Wonder Woman placed fifth on IGN's Top 100 Comic Book Heroes of All Time.^[5]

Publication history[link]

Creation[link]

In an October 25, 1940 interview published in Family Circle titled "Don't Laugh at the Comics", William Moulton Marston described what he saw as the great educational potential of comic books.^[6] This article caught the attention of comics publisher Max Gaines, who hired Marston as an educational consultant for National Periodicals and All-American Publications, two of the companies that would merge to form DC Comics. At that time, Marston decided to develop a new superhero. Family Circle published a follow-up article two years later from issue of the Boston University alumni magazine, it was Marston's wife Elizabeth's idea to create a female superheroine:

William Moulton Marston, a psychologist already famous for inventing the polygraph (forerunner to the magic lasso), struck upon an idea for a new kind of superhero, one who would triumph not with fists or firepower, but with love. "Fine," said Elizabeth. "But make her a woman."^[7]

Marston introduced the idea to Gaines, co-founder of All-American Publications. Given the go-ahead, Marston developed Wonder Woman with Elizabeth, whom Marston believed to be a model of that era's unconventional, liberated woman.^[7] Marston was also inspired by Olive Byrne, who lived with the couple in a polygamous/polyamorous relationship.^[8] Both women served as exemplars for the character and greatly influenced the character's creation.^[7] Wonder Woman debuted in All Star Comics #8 (December 1941), scripted by Marston and with art by Harry G. Peter.

Marston was the creator of a systolic-blood-pressure-measuring apparatus, which was crucial to the development of the polygraph (lie detector). Marston's experience with polygraphs convinced him that women were more honest and reliable than men and could work more efficiently.^[9]

"Wonder Woman is psychological propaganda for the new type of woman who should, I believe, rule the world," Marston wrote.^[1] Although Gloria Steinem placed Wonder Woman on the first standalone cover of Ms. in 1972, Marston, writing in an earlier time, designed Wonder Woman to represent a particular form of female empowerment. Feminism argues that women are equal to men and should be treated as such; Marston's representative of femininity is a 6-foot-tall Amazon wielding a golden lasso that forces obedience on those it encircles.^{[neutrality is disputed]} In Marston's mind, women not only held the potential to be as good as men but to be superior to men.^{[original research?]}

In a 1943 issue of The American Scholar, Marston wrote:

Not even girls want to be girls so long as our feminine archetype lacks force, strength, and power. Not wanting to be girls, they don't want to be tender, submissive, peace-loving as good women are. Women's strong qualities have become despised because of their weakness. The obvious remedy is to create a feminine character with all the strength of Superman plus all the allure of a good and beautiful woman.

During this period, Wonder Woman joined the Justice Society of America as the female member,^[10] albeit as the group's secretary, since the custom was that characters who had their own comic books would hold only honorary membership.

Evolution of the character[link]

Initially, Wonder Woman was an Amazon champion who wins the right to return Steve Trevor — a United States intelligence officer whose plane had crashed on the Amazons' isolated island homeland — to "Man's World" and to fight crime and the evil of the Nazis.

During the Silver Age, Wonder Woman's origin was revamped,^[11] along with other characters'. The new origin story increased the character's Hellenic and mythological roots: receiving the blessing of each deity in her crib, Diana is destined to become "beautiful as Aphrodite, wise as Athena, stronger than Hercules, and swifter than Mercury."^[12]

At the end of the 1960s, under the guidance of Mike Sekowsky, Wonder Woman surrendered her powers in order to remain in Man's World rather than accompany her fellow Amazons to another dimension. Becoming a mod boutique owner, the powerless Diana Prince acquired a Chinese mentor named I Ching. Under I Ching's guidance, Diana learned martial arts and weapons skills and engaged in adventures that encompassed a variety of genres, from espionage to mythology.

Due in part to popular demand -- including Gloria Steinem choosing to feature the original super-powered version of Wonder Woman on the cover of the first issue of her Ms. Magazine -- in the early 1970s the character returned to her superhero roots in Justice League of America and to the World War II era in her own title.

Following the 1985 Crisis on Infinite Earths series, George Pérez, Len Wein, and Greg Potter relaunched the character, writing Wonder Woman as an emissary and ambassador from Themyscira to Patriarch's World, charged with the mission of bringing peace to the outside world.

In August 2010 (issue #600), DC Comics replaced the character's iconic stars-and-stripes singlet with a blue jacket (later discarded), red and gold top and dark pants, retaining only her tiara and lasso.^[13]

In 2011, DC Comics relaunched its entire line of publications to attract a new generation of readers. In this new continuity, Wonder Woman wears a costume similar to her original costume. Also, her origin is significantly changed and she is no longer a clay figure brought to life by the magic of the gods. Instead, she is a demigod, the natural-born daughter of Hippolyta and Zeus.

Powers and abilities[link]

Pre-Crisis[link]

Originally, Wonder Woman owed her abilities to the goddess Aphrodite creating Amazons superior to men, with Diana being the best of their kind.

The Golden Age Wonder Woman was later updated by Marston to be able to will a tremendous amount of brain energy into her muscles and limbs because of her Amazon training, endowing her with extraordinary strength and speed. According to her first appearance, she is stronger and more agile than a hundred of the best human athletes. In Sensation Comics #6 (June 1942), she is able to tear a steel door off its hinges. In one of her earliest appearances, she is shown running easily at 60 mph.^[14] In the same comic, she jumps from a building and lands on the balls of her feet. She can even type at a rate of over 160 words a minute during a test given to her. It was implied, and ultimately confirmed, that any woman who underwent Amazon training would gain superhuman strength.^[15] The TV series took up this notion,^[16] and in the first episode of Super Friends, Diana states to Aquaman, "...the only thing that can surpass super strength is the power of the brain." In early Wonder Woman stories,^[17] Amazon training involves strengthening this ability using pure mental energy.

Her powers would be removed in accordance with "Aphrodite's Law" if she allowed herself to be bound or chained by a male. However the effects of this varied.^[18]

In the television series, her magic belt allowed her to retain her powers when she was not on Paradise Island; removing it weakened her.^[16] Also, she had no powers when she was her alter ego Diana Prince; there was no given explanation for this.

In the comic books, with the inclusion of Wonder Girl and "Wonder Tot" in Diana's back-story, writers provided new explanations of her powers; the character became capable of feats which her sister Amazons could not equal. Wonder Woman (vol. 1) #105 reveals that Diana was formed from clay by the Queen of the Amazons and was imbued with the attributes of the Greek and Roman gods by Athena — "beautiful as Aphrodite, wise as Athena, swifter than Hermes, and stronger than Hercules."^[12] Wonder Woman's Amazon training also gave her limited telepathy, profound scientific knowledge,^[12] and the ability to speak every language known to man and beyond. She was even fluent in caveman^[12][19] and Martian.^[19]

Although Wonder Woman's mythos was returned to its original interpretation between 1966 and 1967, new abilities were added: super breath, the ability to blow jet streams or transform water into snow, which apparently came from Hercules; ventriloquism; imperviousness to extremes of heat and cold; the ability to ride the air currents as if flying, even sensing air updrafts with her fingers; telepathy, including the ability to project images; microscopic vision; the ability to vibrate into another dimension; the ability to bestow wisdom to other beings; the ability to throw her tiara with such skill it could stop bullets; and others, according to the Encyclopedia of Comic Book Heroes.^[20]

Depending on the writer, Diana's invulnerability and power varied greatly according to the needs of the story. Throughout the late 1950s and early 1960s, Robert Kanigher, for example, portrayed Wonder Woman as being so strong that she, after standing atop her hovering plane and lassoing it with her magic lasso, was able to effortlessly lift Themyscira out of the way of an approaching tsunami using just one hand. As prominently featured in all existing Wonder Woman Showcase (Volumes 1 to 4) her strength and even speed seem to be limitless. She could lift and throw buildings and houses. Lasso and swirl huge items like Ferris' wheels and Icebergs. She was able to make a coin into a bridge with her strength, or drill through a mountain within seconds, as well as hurl spaceships with enough accuracy she could bowl over a whole fleet. Her fingernails could cut through a steel door.^[21] She was even able to flip straight over while nearly paralyzed, and split a tree falling on her with her Amazonian boots.^[22] Kanigher showed Wonder Woman as a preteen able to lift whales, push a ship away from a whirlpool, and also as a toddler able to blow so hard on her birthday cake that she sent it into orbit.^[23]

In the Silver and Bronze ages of comics, Wonder Woman was able to further increase her strength. She was unable to remove her bracelets without going insane. In times of great need, however, she would do just that, in order to temporarily augment her power tenfold. Since she would become a threat to friend and foe alike, she would use Amazonian berserker rage only as a weapon of last resort.^[24]

Before Crisis on Infinite Earths there were two Wonder Women: the first one lived on Earth-Two; the second, on Earth-One. The first canonical appearance of the Earth-One Wonder Woman is Wonder Woman (vol. 1) #80 (February 1956). Their first published meeting is Justice League of America (vol. 1) #100 (August 1972); however, their earliest meeting within the DC continuity is Wonder Woman (vol. 1) #228 (February 1977), which takes place in 1943, prior to the events of the Justice League of America story.

Post-Crisis[link]

Wonder Woman's body is a mystical creation made from the clay surrounding Themyscira. Through divine means, her disembodied soul was nurtured in and retrieved from the Cavern of Souls.^[25] Once the soul was placed into the body, it immediately came to life and was blessed with metahuman abilities by six Olympian deities.

Demeter, the goddess of agriculture and fertility, blessed Diana with strength drawn from the Earth spirit Gaea, making her one of the physically strongest heroes in the DC Universe and the strongest female herione of all (John Byrne/ Paul Soriano from Wonder Woman)in the DC Universe.^[26] She has been observed assisting in preventing large chunks of the Moon from crashing onto the Earth,^[27] supporting the weight of bridges,^[28] or hefting entire railroad trains.^[28] and hold her own against beings such as Superman and Captain Marvel. Furthermore, unlike most of her contemporaries in Man's World, Diana is willing to use deadly force, which gives her more options to deal with opponents as circumstances dictate.

While not invulnerable, she is capable of withstanding great concussive force,^[26] shrugging off high-powered rifle fire with some pain but little injury,^{[citation needed]} being knocked through a building, and even surviving a warp-core explosion.^{[citation needed]} She is durable enough to survive the rigors of space until she runs out of breath. While her superhuman strength affords her great resistance to blunt-force trauma, her skin can be cut by weapons if they are sharp enough. Her muscles do not produce lactic acids, giving her great stamina. This allowed her to once battle a clone of Doomsday.

Aphrodite, the goddess of love and beauty, blessed Diana with great beauty and a loving heart.

Pallas Athena, the goddess of wisdom and war, granted Diana great wisdom, intelligence, and military prowess. Athena's gift has enabled Diana to master over a dozen languages (including those of alien origin), multiple complex crafts, sciences and philosophies, as well as leadership, military strategy, and armed and unarmed combat. She can mimic voices, although it is more difficult for her to mimic a man's voice. More recently, Athena bound her own eyesight to Diana's, granting her increased empathy.^[29]

Artemis, goddess of the hunt, animals, and the Moon, graced Diana with the Eyes of the Hunter and Unity with Beasts. The Eyes of the Hunter ability gives Diana a full range of enhanced senses, including telescopic vision and super hearing. Unity with Beasts grants her the ability of empathy particularly that to communicate with all forms of animal life and to calm even the most ferocious of beasts.^[28]

Hestia, goddess of hearth and home, granted Diana "sisterhood with fire, that it might open men's hearts to her." This power has been shown to control the "Fires of Truth," which Diana wields through her lasso, making anyone bound by it unable to lie. This ability also grants her resistance to both normal and supernatural fire.^{[citation needed]}

Hermes, the messenger god of speed, granted Diana superhuman speed and the ability to fly. She is one of the fastest beings (obviously inferior to the Flash Family and an equal to Superman). By concentrating, Diana can mystically defy the laws of gravity and propel herself through the air to achieve flight. She is capable of flying at speeds approaching half the speed of light.^[26] She is swift enough to deflect bullets, lasers, and other projectiles with her virtually impenetrable bracelets. Her brain can process information at an incredibly fast rate. She had many speed blitz showcases mostly with Superman and The Flash. In recent Justice League stories, she even kept up with the Flash and the two also used their superspeed to save a city in The Brave and The Bold.

Diana possesses the ability to relieve her body of physical injury and toxins by becoming one with the Earth's soil and then reforming her body whole again.^[30] During John Byrne's run, it was stated that this is a ritual so sacred that it is used only in the most dire of circumstances.^[31]

She is able to astrally project herself into various lands of myth.^[32] Her physical body reacts to whatever happens to her on the mythical astral plane, leaving her body cut, bruised, or sometimes strengthened once her mind and body are reunited. She can apparently leave the planet through meditation, and did this once to rescue Artemis while she was in hell.

Skills[link]

All versions of Diana depict her as a masterful athlete, acrobat, fighter and strategist, trained and experienced in many ancient and modern forms of armed and unarmed combat, including exclusively Amazonian martial arts. Batman even noted that she is the greatest Melee fighter of all. In some versions, her mother trained her, as Wonder Girl, for a future career as Wonder Woman. From the beginning, she is portrayed as highly skilled in using her Amazon bracelets to stop bullets and in wielding her golden lasso.^[33] She is a superior warrior who has beaten Batman, Big Barda, and Black Canary in sparring matches. The modern version of the character is known to use lethal force when she deems it necessary.^[34]

Weapons[link]

Diana has an arsenal of powerful god-forged weapons at her disposal, but her signature weapons are her indestructible bracelets and the Lasso of Truth.

Her bulletproof bracelets were formed from the remnants of Athena's legendary shield, the Aegis, to be awarded to her champion. The shield was made from the indestructible hide of the great she-goat, Amalthea, who suckled Zeus as an infant. These forearm guards have thus far proven indestructible and able to absorb the impact of incoming attacks, allowing Wonder Woman to deflect automatic weapon fire and energy blasts.^[35] Diana can also slam the bracelets together to create a wave of concussive force capable of making Superman's ears bleed.^[34] Recently, she gained the ability to channel Zeus's lightning through her bracelets as well. Zeus explained to her that this power had been contained within the bracelets since their creation, because they were once part of the Aegis, and that he had only recently unlocked it for her use.^[36]

The Lasso of Truth, or Lariat of Hestia, was forged by Hephaestus from the golden girdle of Gaea.^[28] It is virtually indestructible;^[28] the only times it has been broken were when truth itself was challenged, such as when she confronted Rama Khan of Jarhanpur,^[37] and by Bizarro in Matt Wagner's non-canonical Batman/Superman/Wonder Woman: Trinity.^[38] In Sensation Comics #6 (June 1942), Hippolyta claims that not even Hercules can break it. The Lasso burns with a magical aura called the Fires of Hestia, forcing anyone within the Lasso's confines to be truthful. It also at one time had the power to force anyone caught to obey any command given them, even overriding other kinds of mind control; this was effective enough to defeat strong-willed beings like Captain Marvel.^[39] Diana wields the lasso with great precision and accuracy and can use it as a whip or noose.

As early as the 1950s,^[23] Wonder Woman's Golden Tiara has also doubled as a dagger and a throwing weapon, returning to her like a boomerang.^[28] Its sharpness and mystical nature proved enough to cut even Superman.^[34]

Diana once possessed the Sandals of Hermes, or talaria, which granted the wearer great speed and flight, and the ability to travel beyond the mystical veil that protected the island of Themiscyra from Man's World. They were passed on first to Artemis and later to Wonder Girl. Diana also once possessed the Gauntlets of Atlas, which magnify the physical strength and stamina of the wearer; they too were passed on.

The Golden, Silver, and Bronze Age portrayals of Wonder Woman showed her using an Invisible Airplane that could be controlled by mental command. It was variously described as being either a creation of Amazon technology or the legendary winged horse Pegasus transformed into an aircraft. Its appearance varied as well; originally it had a propeller, while later it was drawn as a jet aircraft resembling a fighter plane. The post-Crisis or Modern Age Wonder Woman has continued to use the Invisible Plane, in the form of a small lightweight disc of alien (Lansinar) technology that, when triggered by her thoughts, transforms into a transparent version of whatever object or vehicle is appropriate for her needs. This disc was revealed to be a sentient life-form. Following the "One Year Later" continuity jump, Diana was given a new invisible plane, created by Wayne Industries, because her original invisible plane was stuck on Themyscira.

Diana occasionally uses additional weaponry in formal battle, such as ceremonial golden armor with golden wings, war-skirt, chest-plate, and a golden helmet in the shape of an eagle's head. She also possesses a sword forged by Hephaestus that is sharp enough to cut the electrons off an atom.^[28]

As a recent temporary inductee into the Star Sapphires, Wonder Woman gained access to the violet power ring of love. This ring allowed her to alter her costume at will, create solid-light energy constructs, and reveal a person's true love to them. She was able to combine the energy with her lasso to enhance its ability.
