Hourglass in a three-legged stand

An hourglass (sandglass, sand timer, sand clock, egg timer) measures the passage of a few minutes or an hour of time. It has two connected vertical glass bulbs allowing a regulated trickle of material from the top to the bottom. Once the top bulb is empty, it can be inverted to begin timing again. The name hourglass comes from historically common hour timing. Factors affecting the time measured include the amount of sand, the bulb size, the neck width, and the sand quality. Alternatives to sand are powdered eggshell and powdered marble^[1] (sources disagree on the best material). In modern times, hourglasses are ornamental, or used when an approximate measure suffices, as in egg timers for cooking or for board games.

History[link]

Temperance bearing an hourglass; detail of Lorenzetti's Allegory of Good Government, 1338

The origin of the hourglass is unclear, although it may have been introduced to Europe by an 8th-century monk named Luitprand, who served at the cathedral in Chartres, France.^[2] It was not until the 14th century that the hourglass was seen commonly, the earliest firm evidence being a depiction in the 1338 fresco Allegory of Good Government by Ambrogio Lorenzetti.^[3] Unlike its predecessor the clepsydra, or water clock, which may have been invented in ancient Egypt, the hourglass is believed to have originated in medieval Europe.^[4] This theory is based on the fact that the first written records of it were mostly from logbooks of European ships.^[4] Written records from the same period mention the hourglass, and it appears in lists of ships stores. An early record is a sales receipt of Thomas de Stetesham, clerk of the English ship La George, in 1345:

"The same Thomas accounts to have paid at Lescluse, in Flanders, for twelve glass horologes (" pro xii. orlogiis vitreis "), price of each 4½ gross', in sterling 9s. Item, For four horologes of the same sort (" de eadem secta "), bought there, price of each five gross', making in sterling 3s. 4d."^[5]

Hourglasses were very popular on board ships, as they were the most dependable measurement of time while at sea. Unlike the clepsydra, the motion of the ship while sailing did not affect the hourglass. The fact that the hourglass also used granular materials instead of liquids gave it more accurate measurements, as the clepsydra was prone to get condensation inside it during temperature changes.^[6] Seamen found that the hourglass was able to help them determine longitude, distance east or west from a certain point, with reasonable accuracy.^[6]

The hourglass also found popularity on land as well. As the use of mechanical clocks to indicate the times of events like church services became more common, creating a ‘need to keep track of time’, the demand for time-measuring devices increased. Hourglasses were essentially inexpensive, as they required no rare technology to make and their contents were not hard to come by, and as the manufacturing of these instruments became more common, their uses became more practical.^[6]

Hourglasses were commonly seen in use in churches, homes, and work places to measure sermons, cooking time, and time spent on breaks from labor.^[4] Because they were being used for more everyday tasks, the model of the hourglass began to shrink. The smaller models were more practical and very popular as they made timing more discreet.

After 1500 A.D., the hourglass was not as widespread as it had been. This was due to the development of the mechanical clock, which became more accurate, smaller and cheaper, and made keeping time easier.^[2] The hourglass, however, did not disappear entirely. Although they became relatively less useful as clock technology advanced, hourglasses remained desirable in their design. Some of the most famous hourglasses are the twelve-hour hourglass of Charlemagne of France and the hourglasses of Henry the VIII of England, made by the artist Holbein in the 16th century.^[2] The oldest known surviving hourglass resides in the British Museum in London.^[4]

Not until the 18th century did the Harrison brothers, John and James, come up with a marine chronometer that significantly improved on the stability of the hourglass at sea. Taking elements from the design logic behind the hourglass, they were able to invent a marine chronometer that was able to accurately measure the journey from England to Jamaica, with only a miscalculation of five seconds, in 1761.^[2]

Design[link]

The shape behind the hourglass has hardly any written evidence of why its external form is the shape that it is. The glass bulbs used, however, have changed in style and design over time. While the main designs have always been ampoule in shape, the bulbs were not always connected. The first hourglasses were two separate bulbs with a cord wrapped at their union that was then coated in wax to hold the piece together and let sand flow in between.^[2] It was not until 1760 that both bulbs were blown together to keep moisture out of the bulbs and regulate the pressure within the bulb that varied the flow of the granular substance.^[6]

Material[link]

While some hourglasses actually did use sand as the granular mixture to measure time, many did not use sand at all. The material used in most bulbs was a combination of “powdered marble, tin/lead oxides, and pulverized, burnt eggshell”.^[4] Over time, different textures of granule matter were tested to see which gave the most constant flow within the bulbs. It was later discovered that for the perfect flow to be achieved the ratio of granule bead to the width of the bulb neck needed to be 1/12 or more but not greater than 1/2 the neck of the bulb.^[7]

Practical uses[link]

3-minute egg timer

Hourglasses were an early dependable, reusable and accurate measure of time. The rate of flow of the sand is independent of the depth in the upper reservoir, and the instrument will not freeze in cold weather.^[4]

From the 15th century onwards, they were being used in a range of applications at sea, in the church, in industry and in cookery.

During the voyage of Ferdinand Magellan around the globe, his vessels kept 18 hourglasses per ship. It was the job of a ship's page to turn the hourglasses and thus provide the times for the ship's log. Noon was the reference time for navigation, which did not depend on the glass, as the sun would be at its zenith.^[8] More than one hourglass was sometimes fixed in a frame, each with a different running time, for example 1 hour, 45 minutes, 30 minutes, and 15 minutes.

Modern practical uses[link]

While they are no longer widely used for keeping time, some institutions do maintain them. Both houses of the Australian Parliament use three hourglasses to time certain procedures, such as divisions.^[9]

The sandglass is still widely used as the kitchen egg timer; for cooking eggs, a three minute timer is typical,^[10] hence the name "egg timer" for three minute hourglasses. Egg timers are sold widely as souvenirs.^{[citation needed]}

The Timewheel in Budapest, Hungary.

Sand timers are also sometimes used in games such as Pictionary and Boggle to implement a time constraint on rounds of play, and provide a sense of urgency to the game of Quicksand.

Symbolic uses[link]

Pirate Christopher Moody's "Bloody Red" jack, c. 1714

Unlike most other methods of measuring time, the hourglass concretely represents the present as being between the past and the future, and this has made it an enduring symbol of time itself.

The hourglass, sometimes with the addition of metaphorical wings, is often depicted as a symbol that human existence is fleeting, and that the "sands of time" will run out for every human life.^[11] It was used thus on pirate flags, to strike fear into the hearts of the pirates' victims. In England, hourglasses were sometimes placed in coffins,^[12] and they have graced gravestones for centuries. The hourglass was also used in alchemy as a symbol for hour.

Modern symbolic uses[link]

Recognition of the hourglass as a symbol of time has survived its obsolescence as a timekeeper. For example, the American television soap opera Days of our Lives, since its first broadcast in 1965, has displayed an hourglass in its opening credits, with the narration, "Like sands through the hourglass, so are the days of our lives," spoken by Macdonald Carey.

Various computer graphical user interfaces may change the pointer to an hourglass during a period when the program is in the middle of a task, and may not accept user input. During that period other programs, for example in different windows, may work normally. When a Windows hourglass does not disappear, it suggests a program is in an infinite loop and needs to be terminated, or is waiting for some external event (such as the user inserting a CD). Unicode has an HOURGLASS symbol at U+231B (⌛).

Hourglass motif[link]

Because of its symmetry, graphic signs resembling an hourglass are seen in the art of cultures which never encountered such objects. Vertical pairs of triangles joined at the apex are common in Native American art; both in North America,^[13] where it can represent, for example, the body of the Thunderbird or (in more elongated form) an enemy scalp,^[14][15] and in South America, where it is believed to represent a Chuncho jungle dweller.^[16] In Zulu textiles they symbolise a married man, as opposed to a pair of triangles joined at the base, which symbolise a married woman.^[17] Neolithic examples can be seen among Spanish cave paintings.^[18][19] Observers have even given the name "hourglass motif" to shapes which have more complex symmetry, such as a repeating circle and cross pattern from the Solomon Islands.^[20]

Hourglass body shape[link]

Hourglass also refers to a body shape of women. In this shape bust and hip are significantly large with narrow waist resembling the shape of an hourglass. A common measurement of shape is 36 24 36 (size in inches). Even clothes to hug body of hourglass shape are available such as an hourglass corset.

Duane Allman (born Howard Duane Allman; November 20, 1946 – October 29, 1971) was an American guitarist, session musician and the primary co-founder and leader of the The Allman Brothers Band, until his early death in a motorcycle accident in 1971 at the age of 24.

ABB was formed in 1969 and, unusually for the time, based in the Southeastern United States. In the early 1970s the band was hugely successful. Duane is best remembered for his brief but influential tenure in that band and in particular for his expressive slide guitar playing and inventive improvisational skills.^[1] In 2003, Rolling Stone magazine ranked Allman at #2 in their list of the 100 greatest guitarists of all time, second only to Jimi Hendrix and in 2011 he was ranked #9.^[2] His tone (achieved with a Gibson Les Paul and two 50-watt bass Marshall amplifiers) was named one of the greatest guitar tones of all time by Guitar Player.^[3]

A sought-after session musician both before and during his tenure with the band, Duane Allman performed with such established stars as King Curtis, Aretha Franklin, Wilson Pickett, and Herbie Mann. He also contributed heavily to the 1970 album Layla and Other Assorted Love Songs by Derek and the Dominos.

Duane Allman’s skills as a guitarist were complemented by personal qualities such as his intensity, drive and ability to draw the best out of others in making music.^[4] He is still referred to by his nickname "Skydog".^[5]

Early years[link]

Duane Allman was born November 20, 1946 in Nashville, Tennessee. He was the eldest son of Willis Allman, a career United States Army sergeant, and Geraldine (née Robbins). His younger brother Gregg Allman was born in late 1947.

While the family were living near Norfolk, Virginia, his father was murdered by a fellow veteran hitchhiker.^[6] In order to retrain as an accountant, Geraldine "Mama A" Allman sent Duane and Gregg to Castle Heights Military Academy in Lebanon, Tennessee, which they both disliked intensely.^[7] In 1957, the family moved to Daytona Beach, Florida where the boys attended Seabreeze High School.

The boys returned to Nashville to spend summers with their grandmother where Gregg learned guitar basics from a neighbour. In 1960, Gregg had saved enough money to buy his first guitar, a Japanese-made Teisco Silvertone while Duane acquired a Harley 165 motorbike which he soon wrote off. So Duane began to take an interest in the guitar leading to fights over it and eventually their mother bought Duane a Gibson Les Paul Junior.^[8]

It was also in Nashville that the boys became musically inspired by a rhythm and blues concert they attended, at which blues guitar legend B. B. King performed. Apparently, Duane turned to Gregg and said, "We got to get into this." ^[8]

Duane learned to play very quickly and soon became the better guitarist of the two, dropping out of high school to stay home during the day and focus on developing his guitar skills.

Allman Joys and Hour Glass[link]

The two Allman brothers started playing publicly in 1961, joining or forming a number of small, local groups. Shortly thereafter, Duane quit high school to stay home during the day and focus on his guitar playing. Their band the Escorts opened for The Beach Boys in 1965 but disbanded and eventually became the Allman Joys. After Gregg graduated from Seabreeze High School in 1965, the Allman Joys went on the road, performing throughout the Southeast and eventually being based in Nashville and St. Louis, Missouri.

The Allman Joys morphed into another not-completely-successful band, The Hour Glass, which moved to Los Angeles in early 1967. There the Hour Glass produced two albums that left the band unsatisfied. Liberty, their record company, tried to market them as a pop band, completely ignoring the band's desire to play more blues-oriented material.

In 1968, Gregg Allman went to visit Duane on his 22nd birthday. Duane was sick in bed. Gregg brought along a bottle of Coricidin pills for his fever and the debut album by guitarist Taj Mahal as a gift. "About two hours after I left, my phone rang," Gregg states. "Baby brother, baby brother, get over here now!" When Gregg got there, he found that Duane had poured the pills out of the bottle, washed off the label and was using it as a slide to play "Statesboro Blues", an old Blind Willie McTell song that Taj Mahal covered. "Duane had never played slide before," says Gregg, "he just picked it up and started burnin'. He was a natural."^{[citation needed]} The song would go on to become a part of the Allman Brothers Band's repertoire, and Duane's slide guitar became crucial to their sound.

The Hour Glass broke up in early 1968, and Duane and Gregg Allman went back to Florida, where they played on demo sessions with the 31st of February, a folk rock outfit whose drummer was Butch Trucks. Gregg returned to California to fulfill Hour Glass obligations, while Duane jammed around Florida for months but didn't get another band going.

Session musician[link]

Allman's playing on the two Hour Glass albums and an Hour Glass session in early 1968 at FAME Studios in Muscle Shoals, Alabama, had caught the ear of Rick Hall, owner of FAME. In November 1968 Hall hired Allman to play on an album with Wilson Pickett. Allman's work on that album, Hey Jude (1968), got him hired as a full-time session musician at Muscle Shoals and brought him to the attention of a number of other musicians, such as Eric Clapton, who later said, "I remember hearing Wilson Pickett's 'Hey Jude' and just being astounded by the lead break at the end. I had to know who that was immediately—right now."

Allman's performance on "Hey Jude" blew away Atlantic Records producer and executive Jerry Wexler when Hall played it over the phone for him. Wexler immediately bought Allman's recording contract from Hall and wanted to use him on sessions with all sorts of Atlantic R&B artists. While at Muscle Shoals, Allman was featured on releases by a number of artists, including Clarence Carter, King Curtis, Aretha Franklin, Laura Nyro, Wilson Pickett, Otis Rush, Percy Sledge, Johnny Jenkins, Boz Scaggs, Delaney & Bonnie and jazz flautist Herbie Mann. Shortly after he recorded the lead break in "Hey Jude", he recorded all of the lead guitar in Boz Scaggs' "Loan Me a Dime". For his first sessions with Aretha, Allman traveled to New York, where in January 1969 he went as an audience member to the Fillmore East to see Johnny Winter and told fellow Shoals guitarist Jimmy Johnson that in a year he'd be on that stage. That December, the Allman Brothers Band indeed played the Fillmore.

Formation of The Allman Brothers Band[link]

The limits of full-time session playing frustrated Allman. The few months in Muscle Shoals were by no means a waste, however; besides meeting the great artists and other industry professionals he was working with, Allman had rented a small, secluded cabin on a lake and spent many solitary hours there refining his playing. Perhaps most significantly, Allman got together with R&B and jazz drummer Jaimoe Johanson, who came to meet Allman at the urging of Otis Redding's manager, Phil Walden, who by now was managing Allman and wanted to build a three-piece band around him. Allman and Jaimoe got Chicago-born bassist Berry Oakley to come up from Florida and jam as a trio, but Berry was committed to his rock band with guitarist Dickey Betts, the Second Coming, and returned south.

Getting fed up with Muscle Shoals, in March Allman took Jaimoe with him back to Jacksonville, Florida, where they moved in with Butch Trucks. Soon a jam session of these three plus Betts, Oakley, and Reese Wynans took place and forged what all present recognized as a natural, or even magical, bond. With the addition of brother Gregg, called back from Los Angeles to sing and replace Wynans on keyboards, at the end of March 1969, the Allman Brothers Band was formed. (Wynans became well known over a decade later as organist with Stevie Ray Vaughan & Double Trouble.) After a bit of rehearsing and gigging, the sextet moved to Macon, Georgia, in April to be near Walden and his Capricorn Sound Studios. While living in Macon, Allman met Donna Roosman, who bore his only child, Galadrielle. Despite their child, the relationship quickly ended.

[edit] Success: Layla, At Fillmore East

The Allman Brothers Band went on to become one of the most influential rock groups of the 1970s, described by Rolling Stone's George Kimball in 1971 as "the best damn rock and roll band this country has produced in the past five years."^[9] After months of nonstop rehearsing and gigging, including free shows in Macon's Central City Park and Atlanta's Piedmont Park, the group was ready to settle on the Allman Brothers Band name, and to record. Their debut album, The Allman Brothers Band, was recorded in New York in September 1969 and released a few months later. In the midst of intense touring, work began in Macon and Miami (Atlantic South - Criteria Studios), and a little bit in New York, on the band's second album, Idlewild South. Produced mostly by Tom Dowd, Idlewild South was released in August 1970 and broke new ground for them by quickly hitting the Billboard charts.

A group date in Miami, also that August, gave Allman the chance to participate in Eric Clapton's Layla and Other Assorted Love Songs. Clapton had long wanted to meet Allman; when he heard that the Allman Brothers were due to play in Miami, where he had just started work on Layla with producer Tom Dowd, he insisted on going to see their concert, where he met Allman. At one point, Allman approached Clapton, fully admiring his ability to play guitar as much as Clapton admired his, and cautiously asked Clapton if he could come by the studio to watch. Clapton was in no way reluctant to say yes, as he knew that his masterful playing combined with Allman's would be greater than the sum of its parts. After the show the two bands—the Allman Brothers Band and Derek and the Dominos—returned to Criteria, where Allman and Clapton quickly formed a deep rapport during an all-night jam session.^[10] Allman wound up participating on most of the album's tracks, contributing some of his best-known work. Allman never left the Allman Brothers Band, though, despite being offered a permanent position with Clapton. Allman never toured with Derek and the Dominos, but he did make three appearances with them on December 1, 1970 at the Curtis Hixon Hall in Tampa (Soulmates LP) and the following day at Onondaga County War Memorial, and one appearance (or possibly just Delaney Bramlett or both Duane and Delaney) November 20, 1970^[11] at the Santa Monica Civic Auditorium, California.

In an interview, Duane told listeners how to tell who played what: Eric played the Fender parts and Duane played the Gibson parts. He continued by nonchalantly noting that the Fender had a sparklier sound, while the Gibson produced more of a "full-tilt screech".^[12]

The Allman Brothers went on to record At Fillmore East in March 1971. Meanwhile, Allman continued contributing session work to other artists' albums whenever he could. According to Skydog: the Duane Allman Story, Allman was in the habit of spontaneously dropping in at recording sessions and contributing to whatever was being taped that day. He received cash payments but no recording credits, making it virtually impossible to compile a complete discography of his works.

Allman was well known for his melodic, extended and attention-holding guitar solos. During this period two of his stated influences were Miles Davis and John Coltrane, having listened extensively to Kind of Blue for two years.^[12][13]

As Allman's distinctive electric bottleneck steel sound began to mature it evolved in time into the musical voice of what would come to be known as Southern Rock, being picked up and redefined in their own styles by slide guitarists that included bandmate Dickey Betts (after Duane's passing), Rory Gallagher, Derek Trucks and Gary Rossington of Lynyrd Skynyrd.

Death[link]

Duane Allman was killed in a motorcycle accident only months after the release and initial success of At Fillmore East.^[14] While in the western part of Macon on October 29, 1971 during a band break from touring and recording, Allman was riding his motorcycle at high speed toward an intersection as a flatbed truck carrying a lumber crane approached. The flatbed truck stopped suddenly in the intersection, forcing Duane to swerve his Harley Davidson Sportster motorcycle sharply to the left to avoid a collision. As he was doing so, he struck either the back of the truck or the ball on the lumber crane and was immediately thrown from the motorcycle. The motorcycle bounced up in the air and landed on Allman and proceeded to skid another 90 feet with Duane pinned underneath, crushing his internal organs. Though he was still alive when he arrived at the hospital, despite emergency surgery, he died several hours later from massive internal injuries. He was just weeks from his 25th birthday.

Memorial[link]

After Allman's funeral and some weeks of mourning, the five surviving members of the Allman Brothers Band carried on, resuming live performances and finishing the recording work interrupted by Duane's death. They named their next album Eat a Peach for Duane's response to an interviewer's question: "How are you helping the revolution?" Allman replied: "There ain't no revolution, only evolution, but every time I'm in Georgia I 'eat a peach' for peace." Released in February, 1972, this double album contains a side of live and studio tracks with Allman, two sides of "Mountain Jam", recorded with Duane at the same At Fillmore East stand in March, and a side of tracks by the surviving five member band.

Bass guitarist Berry Oakley died less than 13 months later in a similar motorcycle crash with a city bus, three blocks from the site of Duane Allman's fatal accident. Oakley's remains were laid to rest beside Duane Allman's in Macon, Georgia's Rose Hill Cemetery.

The variety of Allman's session work and Allman Brothers Band bandleading can be heard to good effect on two posthumous Capricorn releases, An Anthology (1972) and An Anthology Volume II (1974). There are also several archival releases of live Allman Brothers Band performances from what the band calls "Duane's Era".

Shortly after Duane's death, Ronnie Van Zant of Lynyrd Skynyrd dedicated the song "Free Bird", to the memory of Duane Allman. Van Zant would sometimes allude to this in concert; in the "Free Bird" performance at Skynyrd's famed 1976 appearance at Knebworth, England, Van Zant says to pianist Billy Powell, "Play it for Duane Allman." Many people assume the song was written about Duane. However, it had actually been written well before Duane died. (Allen Collins wrote the song after his then girlfriend asked him the question "if I leave here tomorrow, would you still remember me?")

In 1973, fans carved the very large letters "REMEMBER DUANE ALLMAN" in a dirt embankment along Interstate Highway 20 near Vicksburg, Mississippi.^[15][16] A photograph was published in Rolling Stone magazine and in the Rolling Stone Illustrated History of Rock & Roll; the carving itself lasted for over ten years.^[17]

In 1998 the Georgia State Legislature passed a resolution designating a stretch of State Highway 19, US 41, within Macon as the "Duane Allman Boulevard" in his honor.^[18]

Country singer Travis Tritt, in the song "Put Some Drive In Your Country" on his debut album, sings "Now I still love old country/I ain't tryin' to put it down/But damn I miss Duane Allman/I wish he was still around."
