  Americas
  The Americas, or America, are lands in the Western hemisphere, also known as the New World.
  In the English language, the Americas refers to the landmasses of North America and South America with their associated islands and regions, whereas America, in current usage, usually refers to the United States of America.
  The Americas cover 8.3% of the Earth's total surface area (28.4% of its land area) and contain about 13.5% of the human population (about 900 million people).
  The specifics of Paleo-Indian migration to and throughout the Americas, including the exact dates and routes traveled, are subject to ongoing research and discussion. The traditional theory has been that these early migrants moved into the Beringia land bridge between eastern Siberia and present-day Alaska around 40,000–17,000 years ago, when sea levels were significantly lowered due to the Quaternary glaciation. These people are believed to have followed herds of now-extinct pleistocene megafauna along ice-free corridors that stretched between the Laurentide and Cordilleran ice sheets. Another route proposed is that, either on foot or using primitive boats, they migrated down the Pacific Northwest coast to South America. Evidence of the latter would since have been covered by a sea level rise of hundreds of meters following the last ice age.

  Antarctica
  Antarctica
  
  This map uses an orthographic projection, near-polar aspect. The South Pole is near the center, where longitudinal lines converge.
  Antarctica (ⁱ/æntˈɑrtɨkə/ or /ænˈtɑːktɨkə/) is Earth's southernmost continent, containing the geographic South Pole. It is situated in the Antarctic region of the Southern Hemisphere, almost entirely south of the Antarctic Circle, and is surrounded by the Southern Ocean. At 14.0 million km² (5.4 million sq mi), it is the fifth-largest continent in area after Asia, Africa, North America, and South America. For comparison, Antarctica is nearly twice the size of Australia. About 98% of Antarctica is covered by ice that averages at least 1 mile (1.6 km) in thickness.
  Antarctica, on average, is the coldest, driest, and windiest continent, and has the highest average elevation of all the continents. Antarctica is considered a desert, with annual precipitation of only 200 mm (8 inches) along the coast and far less inland. The temperature in Antarctica has reached −89 °C (−129 °F). There are no permanent human residents, but anywhere from 1,000 to 5,000 people reside throughout the year at the research stations scattered across the continent. Only cold-adapted organisms survive there, including many types of algae, animals (for example mites, nematodes, penguins, seals and tardigrades), bacteria, fungi, plants, and protista. Vegetation where it occurs is tundra.

  Australia
  Australia ( /əˈstreɪljə/), officially the Commonwealth of Australia, is a country in the Southern Hemisphere comprising the mainland of the Australian continent as well as the island of Tasmania and numerous smaller islands in the Indian and Pacific Oceans. It is the world's sixth-largest country by total area. Neighbouring countries include Indonesia, East Timor and Papua New Guinea to the north; the Solomon Islands, Vanuatu and New Caledonia to the north-east; and New Zealand to the south-east.
  For at least 40,000 years before European settlement in the late 18th century, Australia was inhabited by indigenous Australians, who belonged to one or more of roughly 250 language groups. After discovery by Dutch explorers in 1606, Australia's eastern half was claimed by Great Britain in 1770 and settled through penal transportation to the colony of New South Wales from 26 January 1788. The population grew steadily in subsequent decades; the continent was explored and an additional five self-governing Crown Colonies were established.

  Brittany
  Brittany (French: Bretagne [bʁətaɲ] ( listen); Breton: Breizh, pronounced [brɛjs]; Gallo: Bertaèyn) is a cultural region in the north-west of France. Previously a kingdom and then a duchy, Brittany was united to the Kingdom of France in 1532 as a province. Brittany has also been referred to as Less, Lesser or Little Britain (as opposed to Great Britain). Brittany is considered as one of the six Celtic nations.
  Brittany occupies the northwest peninsula of continental Europe in northwest France. It is bordered by the English Channel to the north, the Celtic Sea and the Atlantic Ocean to the west, and the Bay of Biscay to the south. Its land area is 34,023 km² (13,136 sq mi). The historical province of Brittany is divided into five departments: Finistère in the west, Côtes-d'Armor in the north, Ille-et-Vilaine in the north east, Loire-Atlantique in the south east and Morbihan in the south on the Bay of Biscay.
  In 1956, French regions were created by gathering departments between them. The Region of Brittany comprises, since then, four of the five Breton departments (80% of historical Brittany), while the remaining area of the old Brittany, the Loire-Atlantique department, around Nantes, forms part of the Pays de la Loire region. This territorial organisation is regularly contested. The Kingdom and the Duchy of Brittany, the province of Brittany, and the modern Region of Brittany cover the Western part of Armorica, as it was known during the period of Roman occupation.

  Indian Ocean
  The Indian Ocean is the third largest of the world's oceanic divisions, covering approximately 20% of the water on the Earth's surface. It is bounded on the north by the Indian Subcontinent and Arabian Peninsula (or, more generally, by southern and western Asia); on the west by eastern Africa; on the east by Indochina, the Sunda Islands, and Australia; and on the south by the Southern Ocean (or, depending on definition, by Antarctica). The ocean is named after the geographic location of India.
  As one component of the interconnected global ocean, the Indian Ocean is delineated from the Atlantic Ocean by the 20° east meridian running south from Cape Agulhas, and from the Pacific by the meridian of 146°55' east. The northernmost extent of the Indian Ocean is approximately 30° north in the Persian Gulf. This ocean is nearly 10,000 kilometres (6,200 mi) wide at the southern tips of Africa and Australia; its area is 73,556,000 square kilometres (28,350,000 sq mi), including the Red Sea and the Persian Gulf.

  Netherlands
  The Netherlands (ⁱ/ˈnɛðərləndz/; Dutch: Nederland [ˈneːdə(r)lɑnt] or [ˈneɪ̯də(r)lɑnt] ( listen); West Frisian: Nederlân; Papiamento: Hulanda) is a constituent country of the Kingdom of the Netherlands, located mainly in North-West Europe and with some islands in the Caribbean. Mainland Netherlands borders the North Sea to the north and west, Belgium to the south, and Germany to the east, and shares maritime borders with Belgium, Germany and the United Kingdom. It is a parliamentary democracy organised as a unitary state. The country capital is Amsterdam and the seat of government is The Hague. The Netherlands in its entirety is often referred to as Holland, although North and South Holland are actually only two of its twelve provinces (a case of pars pro toto; see terminology of "the Netherlands").

  New Zealand
  New Zealand (Māori: Aotearoa) is an island country located in the southwestern Pacific Ocean. The country geographically comprises two main landmasses ‒ that of the North and South Islands ‒ as well as numerous smaller islands. New Zealand is situated some 1,500 kilometres (900 mi) east of Australia across the Tasman Sea and roughly 1,000 kilometres (600 mi) south of the Pacific island nations of New Caledonia, Fiji, and Tonga. Because of its remoteness, it was one of the last lands to be settled by humans.
  During its long isolation, New Zealand developed a distinctive biodiversity of both animal and plant life. Most notable are the large number of unique bird species, many of which became extinct after the arrival of humans and introduced mammals. With a mild maritime climate, the land was mostly covered in forest. The country's varied topography and its sharp mountain peaks owe much to the tectonic uplift of land and volcanic eruptions caused by the Pacific and Indo-Australian Plates clashing beneath the earth's surface.

  Northern Hemisphere
  Coordinates: 45°0′0″N 0°0′0″E / 45°N 0°E / 45; 0
  The Northern Hemisphere is the half of a planet that is north of its equator—the word hemisphere literally means “half sphere”. It is also that half of the celestial sphere north of the celestial equator. Earth's northern hemisphere contains most of the planet's land, and roughly 90% of its human population. See also Arctic, Temperate zone, Tropics, Seasons and Climate
  Due to the Earth's axial tilt, winter lasts from the winter solstice (typically December 22) to the vernal equinox (typically March 20), while summer lasts from the summer solstice (typically June 21) through to the autumnal equinox (typically September 21).
  The Arctic is the region north of the Arctic Circle. Its climate is characterized by cold winters and cool summers. Precipitation mostly comes in the form of snow. The Arctic experiences some days in summer when the Sun never sets, and some days during the winter when it never rises. The duration of these phases varies from one day for locations right on the Arctic Circle to several months near the North Pole.

  Pacific Ocean
  The Pacific Ocean is the largest of the Earth's oceanic divisions. It extends from the Arctic in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, bounded by Asia and Australia in the west, and the Americas in the east.
  At 165.2 million square kilometres (64.1 million square miles) in area, this largest division of the World Ocean – and, in turn, the hydrosphere – covers about 46% of the Earth's water surface and about one-third of its total surface area, making it larger than all of the Earth's land area combined. The equator subdivides it into the North Pacific Ocean and South Pacific Ocean, with two exceptions: the Galápagos and Gilbert Islands, while straddling the equator, are deemed wholly within the South Pacific. The Mariana Trench in the western North Pacific is the deepest point in the world, reaching a depth of 10,911 metres (35,797 ft).
  The eastern Pacific Ocean was first sighted by Europeans early in the 16th century. Spanish explorer Vasco Núñez de Balboa crossed the Isthmus of Panama in 1513 and named it Mar del Sur (South Sea). The ocean's current name was given by Portuguese explorer Ferdinand Magellan during the Spanish expedition of world circumnavigation in 1521, who encountered favourable winds as he reached the ocean and called it Mar Pacifico in Portuguese, meaning "peaceful sea".

  Southern hemisphere
  Coordinates: 45°0′0″S 0°0′0″E / 45°S 0°E / -45; 0
  The Southern Hemisphere is the part of Earth that lies south of the equator. The word hemisphere (from the Greek word σφαιρα (sphere) +ημι (half)) literally means 'half ball' or "half sphere". It is also that half of the celestial sphere south of the celestial equator.
  The Southern Hemisphere contains all or parts of four continents (Antarctica, Australia, most parts of South America and southern half of Africa), four oceans (South Atlantic, Indian, South Pacific, and Southern) and most of Oceania. Several islands off the Asian continental mainland are also in the Southern Hemisphere. Due to the tilt of Earth's rotation relative to the Sun and the ecliptic plane, summer is December to March and winter is June to September. September 22 or 23 is the vernal equinox and March 20 or 21 is the autumnal equinox.
  
  
  Climates in the Southern Hemisphere overall tend to be slightly milder than those in the Northern Hemisphere at similar latitudes except in the Antarctic which is colder than the Arctic. This is because the Southern Hemisphere has significantly more ocean and much less land. Water heats up and cools down more slowly than land.

  Spain (ⁱ/ˈspeɪn/ SPAYN; Spanish: España, pronounced: [esˈpaɲa] ( listen)), officially the Kingdom of Spain (Spanish: Reino de España), is a sovereign state and a member of the European Union located in southwestern Europe on the Iberian Peninsula. Its mainland is bordered to the south and east by the Mediterranean Sea except for a small land boundary with the British Overseas Territory of Gibraltar; to the north and north east by France, Andorra, and the Bay of Biscay; and to the northwest and west by the Atlantic Ocean and Portugal.
  Spanish territory also includes the Balearic Islands in the Mediterranean, the Canary Islands in the Atlantic Ocean off the African coast, and two autonomous cities in North Africa, Ceuta and Melilla, that border Morocco. Furthermore, the town of Llívia is a Spanish exclave situated inside French territory. With an area of 504,030 square kilometres (194,610 sq mi), it is the second largest country in Western Europe and the European Union after France, and the fourth largest country in Europe after Russia, Ukraine and France.

  Tierra del Fuego
  Tierra del Fuego ( /tiːˈɛərə dɛl ˈfweɪɡoʊ/, Spanish: [ˈtjera ðel ˈfweɣo]; Spanish for "Fireland" or "Land of Fire") is an archipelago off the southernmost tip of the South American mainland, across the Strait of Magellan. The archipelago consists of a main island Isla Grande de Tierra del Fuego divided between Chile and Argentina with an area of 48,100 km² (18,572 sq mi), and a group of smaller islands including Cape Horn. Initially discovered by Ferdinand Magellan's expedition in 1520, the islands were not settled by people of European descent until the second half of the 19th century at the height of the sheep farming and gold rush booms. Today's economic activity in the northern part of Tierra del Fuego is dominated by petroleum extraction while in the south tourism, manufacturing and Antarctic logistics are important. The numbers of the native Selk'nam and Yaghans were greatly reduced by introduced diseases and by unequal conflicts with settlers. Today the Selk'nam are practically extinct as a distinct people, with all of their very few descendants being mestizos and their language extinct. Some of the few remaining Yaghans have settled in Villa Ukika in Navarino Island, others have scattered across Chile and Argentina. Tierra del Fuego hosts large areas protected as national parks and reserves, most of them in the mountainous south.

  Torres Strait
  The Torres Strait is a body of water which lies between Australia and the Melanesian island of New Guinea. It is approximately 150 km (93 mi) wide at its narrowest extent. To the south is Cape York Peninsula, the northernmost continental extremity of the Australian state of Queensland. To the north is the Western Province of Papua New Guinea.
  The strait links the Coral Sea to the east with the Arafura Sea in the west. Although it is an important international sea lane, it is very shallow, and the maze of reefs and islands can make it hazardous to navigate. In the south the Endeavour Strait is located between Prince of Wales Island (Muralug) and the mainland.
  Several clusters of islands lie in the Strait, collectively called the Torres Strait Islands. There are at least 274 of these islands, of which 17 have present-day permanent settlements. Over 6,800 Torres Strait Islanders live on the Islands and 42,000 live on the mainland.
  These islands have a variety of topographies, ecosystems and formation history. Several of those closest to the New Guinea coastline are low-lying, formed by alluvial sedimentary deposits borne by the outflow of the local rivers into the sea. Many of the western islands are hilly and steep, formed mainly of granite, and are peaks of the northernmost extension of the Great Dividing Range now turned into islands when sea levels rose at the end of the last ice age. The central islands are predominantly coral cays, and those of the east are of volcanic origins. The islands are considered Australian territory and are administered from Thursday Island.

  Abel Tasman
  Abel Janszoon Tasman (Dutch: [ˈaːbəl ˈjɑnsoʊn ˈtɑsmɐn]; 1603–1659) was a Dutch seafarer, explorer and merchant, best known for his voyages of 1642 and 1644 in the service of the VOC (United East India Company). His was the first known European expedition to reach the islands of Van Diemen's Land (now Tasmania) and New Zealand, and to sight the Fiji islands. His navigator François Visscher, and his merchant Isaack Gilsemans, mapped substantial portions of Australia, New Zealand and some Pacific Islands.
  Abel Tasman was born in 1603 in Lutjegast in what is now the province of Groningen, the Netherlands. In 1633, Tasman went to Batavia in service of the VOC; four years later he was back in Amsterdam. Tasman signed on for another ten years and took his wife along to Batavia. In 1639 Tasman was sent as second in command of an exploring expedition in the north Pacific under Matthijs Quast. His fleet included the ships Engel and Gracht and reached Fort Zeelandia (Dutch Formosa) and Deshima.
  In August 1642, the Council of the Indies, consisting of Antonie van Diemen, Cornelis van der Lijn, Joan Maetsuycker, Justus Schouten, Salomon Sweers, Cornelis Witsen, and Pieter Boreel in Batavia despatched Abel Tasman and Franchoijs Visscher on a voyage of which one of the objects was to obtain knowledge of "all the totally unknown provinces of Beach".

• André d'Albaigne
  Francisque and André d’Albaigne were 16th-century Italian merchants from the city of Lucca. Their name was Dalbagnio, according to a notary act of 1567 involving their brother Pellegrino (resident at La Rochelle, France since his marriage to the daughter of Mayor Vincent Nicolas).
  From Lisbon (where he was an agent of the Bonvisi merchant house), Francisque d’Albaigne went to Paris to propose the occupation of a “certain very rich new land of very great extent not yet discovered by the kings of Spain and Portugal”. He had lured cosmographer Bartholomeu Velho from the service of the Portuguese to “demonstrate” to King Charles IX the location of this unknown country. However, Velho died at Nantes on 28 February 1568 and Francisque soon after.

  Aristotle
  Aristotle (Ancient Greek: Ἀριστοτέλης, Aristotélēs) (384 BC – 322 BC) was a Greek philosopher and polymath, a student of Plato and teacher of Alexander the Great. His writings cover many subjects, including physics, metaphysics, poetry, theater, music, logic, rhetoric, linguistics, politics, government, ethics, biology, and zoology. Together with Plato and Socrates (Plato's teacher), Aristotle is one of the most important founding figures in Western philosophy. Aristotle's writings were the first to create a comprehensive system of Western philosophy, encompassing morality, aesthetics, logic, science, politics, and metaphysics.
  Aristotle's views on the physical sciences profoundly shaped medieval scholarship, and their influence extended well into the Renaissance, although they were ultimately replaced by Newtonian physics. In the zoological sciences, some of his observations were confirmed to be accurate only in the 19th century. His works contain the earliest known formal study of logic, which was incorporated in the late 19th century into modern formal logic. In metaphysics, Aristotelianism had a profound influence on philosophical and theological thinking in the Islamic and Jewish traditions in the Middle Ages, and it continues to influence Christian theology, especially the scholastic tradition of the Catholic Church. His ethics, though always influential, gained renewed interest with the modern advent of virtue ethics. All aspects of Aristotle's philosophy continue to be the object of active academic study today. Though Aristotle wrote many elegant treatises and dialogues (Cicero described his literary style as "a river of gold"), it is thought that the majority of his writings are now lost and only about one-third of the original works have survived.

  Ferdinand Magellan
  Ferdinand Magellan (Portuguese: Fernão de Magalhães, IPA: [fɨɾˈnɐ̃w ðɨ mɐɣɐˈʎɐ̃jʃ]; Spanish: Fernando de Magallanes, IPA: [ferˈnando ðe maɣaˈʎanes]; c. 1480 – 27 April 1521) was a Portuguese explorer. He was born in Sabrosa, in northern Portugal, and served King Charles I of Spain in search of a westward route to the "Spice Islands" (modern Maluku Islands in Indonesia).
  Magellan's expedition of 1519–1522 became the first expedition to sail from the Atlantic Ocean into the Pacific Ocean (then named "peaceful sea" by Magellan; the passage being made via the Strait of Magellan), and the first to cross the Pacific. It also completed the first circumnavigation of the Earth, although Magellan himself did not complete the entire voyage, being killed during the Battle of Mactan in the Philippines. (For background see Exploration of the Pacific).
  Magellan also gives his name to the Magellanic Penguin, which he was the first European to note, and the Magellanic clouds, now known to be nearby dwarf galaxies.

  Galician people
  The Galicians (Galician: Galegos) are an ethnic group and nationality, whose historical homeland is Galicia in north-western Spain. Most Galicians are bilingual, speaking both their historic language, Galician, and Castilian Spanish.
  The autonomous community (a concept established in the Spanish constitution of 1978) that is known as (a) Comunidade Autónoma Galega in Galician, and as (la) Comunidad Autónoma Gallega in Spanish (in English: Galician Autonomous Community), is composed of the four Spanish provinces of A Coruña, Lugo, Ourense, and Pontevedra.
  The official Statistical body of Galicia is the Instituto Galego de Estatística (IGE). According to the IGE, Galicia's total population in 2008 was 2,783,100 (1,138,474 in A Coruña, 355.406 in Lugo, 336.002 in Ourense, and 953.218 in Pontevedra). The most important cities in this region, which serve as the provinces' administrative centres, are Vigo, Pontevedra (in Pontevedra), Santiago de Compostela, A Coruña, Ferrol (in A Coruña), Lugo (in Lugo), and Ourense (in Ourense). The official languages are Galician and Spanish. Knowledge of Spanish is compulsory according to the Spanish constitution and virtually universal. Knowledge of Galician, after declining for many years owing to the pressure of Spanish and official persecution, is again on the rise due to favorable official language policies and popular support. Currently about 82% of Galicia's population can speak Galician and about 61% has it as a mother tongue.

  Gaspard de Coligny
  Gaspard de Coligny (16 February 1519 – 24 August 1572), Seigneur (Lord) de Châtillon, was a French nobleman and admiral, best remembered as a disciplined Huguenot leader in the French Wars of Religion.
  Coligny came of a noble family of Burgundy. His family traced their descent from the 11th century, and in the reign of Louis XI, were in the service of the King of France. His father, Gaspard I de Coligny, known as the 'Marshal of Châtillon', served in the Italian Wars from 1494 to 1516, married in 1514, and was created Marshal of France in 1516. By his wife, Louise de Montmorency, sister of the future constable, he had three sons, all of whom played an important part in the first period of the Wars of Religion: Odet, Gaspard and François.
  Born at Châtillon-sur-Loing in 1519, Gaspard came to court at the age of 22 and began a friendship with François of Guise. In the campaign of 1543 Coligny distinguished himself, and was wounded at the sieges of Montmédy and Bains. In 1544 he served in the Italian campaign under the Count of Enghien, and was knighted on the Field of Ceresole. Returning to France, he took part in different military operations; and having been made colonel-general of the infantry (April 1547), exhibited great capacity and intelligence as a military reformer.

  Gerard Mercator
  Gerardus Mercator^{[pronunciation?]} (born 5 March 1512 in Rupelmonde in the Hapsburg County of Flanders, Holy Roman Empire, died 2 December 1594 in Duisburg, United Duchies of Jülich-Cleves-Berg, Holy Roman Empire) was a cartographer. He is remembered for the Mercator projection world map, which is named after him. This proved very useful to many later navigators who could (using his map) sail across the entire ocean on approximately straight paths (called rhumb lines). He died in Duisburg.
  Mercator was born Gerard de gemor or de Cremer in the Flemish town of Rupelmonde to parents from Gangelt in the Duchy of Jülich, where he was raised. "Mercator" is the Latinized form of his name. It means "merchant". He was educated in 's-Hertogenbosch by the famous humanist Macropedius and at the University of Leuven. Despite Mercator's fame as a cartographer, his main source of income came through his craftsmanship of mathematical instruments. In Leuven, he worked with Gemma Frisius and Gaspar Myrica from 1535 to 1536 to construct a terrestrial globe, although the role of Mercator in the project was not primarily as a cartographer, but rather as a highly skilled engraver of brass plates. Mercator's own independent map-making began only when he produced a map of Palestine in 1537; this map was followed by another—a map of the world (1538) – and a map of Flanders (1540). During this period he learned Italic script because it was the most suitable type of script for copper engraving of maps. He wrote the first instruction book of Italic script published in northern Europe.

  Captain James Cook, FRS, RN (7 November 1728 – 14 February 1779) was a British explorer, navigator and cartographer who ultimately rose to the rank of captain in the Royal Navy. Cook made detailed maps of Newfoundland prior to making three voyages to the Pacific Ocean, during which he achieved the first European contact with the eastern coastline of Australia and the Hawaiian Islands, as well as the first recorded circumnavigation of New Zealand.
  Cook joined the British merchant navy as a teenager and joined the Royal Navy in 1755. He saw action in the Seven Years' War, and subsequently surveyed and mapped much of the entrance to the Saint Lawrence River during the siege of Quebec. This helped bring Cook to the attention of the Admiralty and Royal Society. This notice came at a crucial moment in both Cook's career and the direction of British overseas exploration, and led to his commission in 1766 as commander of HM Bark Endeavour for the first of three Pacific voyages.
  In three voyages Cook sailed thousands of miles across largely uncharted areas of the globe. He mapped lands from New Zealand to Hawaii in the Pacific Ocean in greater detail and on a scale not previously achieved. As he progressed on his voyages of discovery he surveyed and named features, and recorded islands and coastlines on European maps for the first time. He displayed a combination of seamanship, superior surveying and cartographic skills, physical courage and an ability to lead men in adverse conditions.

  Jan Janssonius
  Johannes Janssonius (1588, Arnhem – buried July 11, 1664, Amsterdam) (born Jan Janszoon, in English usually Jan Jansson) was a Dutch cartographer who lived and worked in Amsterdam in the 17th century.
  Janssonius was born in Arnhem, the son of Jan Janszoon the Elder, a publisher and bookseller. In 1612 he married Elisabeth de Hondt, the daughter of Jodocus Hondius. He produced his first maps in 1616 of France and Italy. In 1623 Janssonius owned a bookstore in Frankfurt am Main, later also in Danzig, Stockholm, Copenhagen, Berlin, Königsberg, Geneva and Lyon. Elisabeth Hondius died in 1627 and he remarried one Elisabeth Carlier in 1629. In the 1630s he formed a partnership with his brother in law Henricus Hondius, and together they published atlases as Mercator/Hondius/Janssonius.
  Under the leadership of Janssonius the Hondius Atlas was steadily enlarged. Renamed Atlas Novus, it had three volumes in 1638, one fully dedicated to Italy. 1646 a fourth volume came out with "English County Maps", a year after a similar issue by Willem Blaeu. Janssons maps are similar to those of Blaeu, and he is often accused of copying from his rival, but many of his maps predate those of Blaeu and/or covered different regions. By 1660, at which point the atlas bore the appropriate name "Atlas Major", there were 11 volumes, containing the work of about a hundred credited authors and engravers. It included a description of "most of the cities of the world" (Townatlas), of the waterworld (Atlas Maritimus in 33 maps), and of the Ancient World (60 maps). The eleventh volume was the Atlas of the Heavens by Andreas Cellarius. Editions were printed in Dutch, Latin, French, and a few times in German.

  Kazakhstania
  Kazakhstania, also known as the Kazakhstan Block, is a small continental region in the interior of Asia. It consists of that area north and east of the Aral Sea, south of the Siberian craton and west of the Altai Mountains and Lake Balkhash. Politically, it comprises most of Kazakhstan and has a total area of around 1.3 million km². The Junggar basin in Xinjiang, China is also part of Kazahstania, though sometimes referred to as the Junggar Block.
  It is believed that present-day Kazakhstania is chiefly a mélange of early Paleozoic volcanic island arcs and some small continental terranes. These were joined together during the Ordovician to form what was at the time an isolated continent of its own. During the Carboniferous and Permian, Siberia collided with Kazakhstania to form the Altai Mountains, later Baltica collided in the Ural orogeny, creating the basis for most of present-day Eurasia.
  Kazakhstania is mainly flat: only in the east near Karaganda are there mountains and these only rise to 1,565 metres (5,130 feet) in the Tarbagatay Range. Although most of Kazakhstania is arid and practically no water flows from the region to the oceans, there is extensive grazing of cattle, sheep and camels on the grasslands which cover most of the region today. Kazakhstania was too dry for extensive glaciation during the Quaternary. Kazakhstania contains as much as a quarter of the world's proven uranium reserves and is also one of the world's major source of lead, zinc, and antimony ores. On the southern boundary in the Turan Depression are large deposits of natural gas formed as a result of its collision with the Indian plate.

• Luis Váez de Torres
  Luís Vaz de Torres (Galician or Portuguese), also Luis Váez de Torres in the Spanish spelling, (born c. 1565; fl. 1607) was a 16th-17th century maritime explorer serving the Spanish Crown, noted for the first recorded navigation of the strait which separates the continent of Australia from the island of New Guinea, and which now bears his name (Torres Strait).
  There is no record of Torres' origins. The year and place of his birth are unknown; assuming him to have been in his late thirties or forties in 1606, a birth year of around 1565 is considered likely.
  Since the 19th century, Torres has been presented by some Portuguese and British historians as Portuguese, without giving any evidence other than his name, which could just as well be Galician. However, all his writings (all are addressed to the Spanish Crown) were in Spanish and no records ever call him a Portuguese, even though the very same records are clear in noting the remarks made by crew members on the Portuguese origins of the expedition's highest commanding officer. Torres is recorded as having been called a "Breton" during the voyage, which points to an origin in the northwest province of Spain, Galicia.

  Martin Waldseemüller
  Martin Waldseemüller (Latinized Martinus Ilacomylus, Ilacomilus or Hylacomylus, c. 1470, Wolfenweiler, Baden – Saint-Dié-des-Vosges, Lorraine 1520, March 16) was a German cartographer. He and Matthias Ringmann are credited with the first recorded usage of the word America, on the 1507 map Universalis Cosmographia in honour of the Florentine explorer Amerigo Vespucci.
  Waldseemüller was born in Wolfenweiler, then his family moved to near Freiburg im Breisgau (his mother came from Radolfzell) and he studied at the University of Freiburg. He died March 16, 1520, "ab intestat", then a canon of the collegiate Church of Saint-Dié (located between Nancy, Lorraine and Strasbourg, Alsace in the heart of the Vosges blue mountain range along the Rhine river valley).
  On April 25, 1507, as a member of the Gymnasium Vosagense at Saint Diey (German: Sankt Didel) in the duchy of Lorraine (today Saint-Dié-des-Vosges, France), he produced a globular world map and a large 12-panel world wall map (Universalis Cosmographia, both bearing the first use of the name "America". The globular and wall maps were accompanied by a book Cosmographiae Introductio, an introduction to cosmography. The book, first printed in the city of Saint-Dié-des-Vosges, includes in its second part, a translation to Latin of the Quattuor Americi Vespuccij navigationes (Four Voyages of Americo Vespucci), which is apparently a letter written by Amerigo Vespucci, although some historians consider it to have been a forgery written by its supposed recipient in Italy. In the chapter nine of the first part of the Cosmographiae Introductio, written by Mat(t)hias Ringmann (died in Sélestat in the year of Our Lord 1511 at the age of 29), it is explained why the name America was proposed for the then New World, or the Fourth Part of the World:

  Matthew Flinders
  Captain Matthew Flinders RN (16 March 1774 – 19 July 1814) was a distinguished navigator and cartographer, who was the first to circumnavigate Australia and identify it as a continent.
  On his first voyage to New South Wales, he made friends with the ship's surgeon George Bass, and the two of them presently sailed through what became the Bass Strait, confirming that Tasmania was an island. In 1801 he was commissioned to chart the whole coastline of New Holland, and he specially noted the fertile land around Port Phillip, today's Melbourne.
  Heading back to England in 1803, his vessel needed urgent repairs at Mauritius. Although Britain and France were at war, Flinders thought the scientific nature of his work would ensure safe passage, but a suspicious governor kept him under arrest for more than six years. In captivity, he recorded details of his voyages for future publication, and put forward his rationale for naming the new continent 'Australia', as an umbrella-term for New Holland and New South Wales - a suggestion taken up later by Governor Macquarie.

  Oronce Fine
  Oronce Fine (or Finé; in Latin, Orontius Finnaeus or Finaeus; Italian: Oronzio Fineo) (20 December 1494 - 8 August 1555) was a French mathematician and cartographer.
  Born in Briançon, the son and grandson of physicians, he was educated in Paris (Collège de Navarre), and obtained a degree in medicine in 1522.
  He was imprisoned in 1524, probably for practicing judicial astrology.
  In 1531, he was appointed to the chair of mathematics at the Collège Royal (the present Collège de France), founded by Francis I of France, where he taught until his death.
  Although primarily a populariser, Fine was one of the most prolific authors of mathematical books of his age. He worked in a wide range of mathematical fields, including practical geometry, arithmetic, optics, gnomonics, astronomy, and instrumentalism.
  He gave the value of pi (= 3.1416) to be (22 2/9)/7 =  3.1746 in 1544. Later, he gave 47/15 =  3.1333 and, in De rebus mathematicis (1556), he gave 3 11/78 = 3.1410.
  In 1542 Fine published De mundi sphaera (On the Heavenly Spheres), a popular astronomy textbook whose woodcut illustrations were much appreciated. His writing on astronomy included guides to the use of astronomical equipment and methods (e.g. the ancient practice of determining longitude through the coordinated observation of lunar eclipses from two fixed points with enough distance between them to make the phenomena appear at different times of the night.) He also described more recent innovations, such as an instrument he called a méthéoroscope (an astrolabe modified by adding a compass).

  Portuguese people
  The Portuguese (Portuguese: os Portugueses) are a nation and ethnic group native to the country of Portugal, in the west of the Iberian peninsula of south-west Europe. Their language is Portuguese, and Roman Catholicism is the predominant religion.
  Due to the large historical extent of the Portuguese Empire and the colonization of territories in Africa, Asia and the Americas, as well as historical and recent emigration, Portuguese communities can be found in many diverse regions around the globe, and a large Portuguese diaspora exists.
  The Portuguese are a southwestern European population, with origins predominantly from Atlantic Europe, Western Europe and the Western Mediterranean.
  The earliest modern humans inhabiting Portugal are believed to have been Paleolithic peoples that may have arrived in the Iberian Peninsula as early as 35,000 to 40,000 years ago. Current interpretation of Y-chromosome and mtDNA data suggests that modern-day Portuguese traces largely a significant amount of these lineages to the paleolithic peoples which began arriving to the European continent between the end of the last glaciation around 45,000 years ago.

  Ptolemy
  Claudius Ptolemy ( /ˈtɒləmi/; Greek: Κλαύδιος Πτολεμαῖος, Klaudios Ptolemaios; Latin: Claudius Ptolemaeus; c. AD 90 – c. AD 168), was a Greek-Roman citizen of Egypt who wrote in Greek. He was a mathematician, astronomer, geographer, astrologer, and poet of a single epigram in the Greek Anthology. He lived in Egypt under Roman rule, and is believed to have been born in the town of Ptolemais Hermiou in the Thebaid. This theory, proposed by Theodore Meliteniotes, could be correct, but it is late (ca. 1360) and unsupported. There is no reason to suppose that he ever lived anywhere else than Alexandria, where he died around AD 168.
  Ptolemy was the author of several scientific treatises, at least three of which were of continuing importance to later Islamic and European science. The first is the astronomical treatise now known as the Almagest (in Greek, Ἡ Μεγάλη Σύνταξις, "The Great Treatise", originally Μαθηματικὴ Σύνταξις, "Mathematical Treatise"). The second is the Geography, which is a thorough discussion of the geographic knowledge of the Greco-Roman world. The third is the astrological treatise known sometimes in Greek as the Apotelesmatika (Ἀποτελεσματικά), more commonly in Greek as the Tetrabiblos (Τετράβιβλος "Four books"), and in Latin as the Quadripartitum (or four books) in which he attempted to adapt horoscopic astrology to the Aristotelian natural philosophy of his day.

  Willem Schouten
  Willem Cornelisz Schouten (c. 1567–1625) was a Dutch navigator for the Dutch East India Company. He was the first to sail the Cape Horn route to the Pacific Ocean.
  Willem Cornelisz Schouten was born in c. 1567 in Hoorn, Holland, Seventeen Provinces.
  In 1615 Willem Cornelisz Schouten and Jacob le Maire sailed from Texel in the Netherlands, in command of an expedition sponsored by Isaac Le Maire and his Australische Compagnie in equal shares with Schouten. A main purpose of the voyage was to search for Terra Australis, which eluded them. A further objective was to evade the trade restrictions of the Dutch East India Company (VOC) by finding a new route to the Pacific and the Spice Islands. In 1616 Schouten rounded Cape Horn, which he named for his birthplace, the Dutch city of Hoorn. He followed the north coasts of New Ireland and New Guinea and visited adjacent islands, including what became known as the Schouten Islands.
  Although he had opened an unknown route, the VOC claimed infringement of its monopoly of trade to the Spice Islands. Schouten was arrested (and later released) and his ship confiscated in Java. On his return he would sail again for the VOC, and on one of these trips he died off the coast of Madagascar in 1625.
