The identification of the constellation with a bull is very old, certainly dating to the Chalcolithic, and perhaps even to the Upper Paleolithic. Variety of myths also lends credence to the fact that bulls have been worshiped since ancient times as symbol of strength and fertility.
Taurus has been observed as the image of a bull from the time of the Chaldeans, some 500 years ago.Taurus was regarded as a sacred Bull of light by the Sumerians.
From their home in Mesopotamia, around 4000 B.C. to 2000 B.C., the ancient Egyptians…..according to history, revered Apis, the Bull of Memphis….a real bull believed to have been the incarnation of Osiris.
In compilation of Greek astronomical knowledge, Ptolemy of Egypt cataloged information concerning Taurus during the Second Century A.D.
During the classical Era, Greeks perceived Taurus constellation as Zeus in the guise of a bull.
Though the Chinese do not regard the constellation as a bull, it is alternatively regarded as “White Tiger” or the “GreatBridge.”
Only the forequarters of the bull are visible in the groups of stars which compose Taurus…a depiction of animal emerging from the waves. The constellation of Cetus and Aries cover the hindquarters of the bull, considered submerged.
It was within Taurus that the Italian astronomer Piazzi made the discovery of the first asteroid named Ceres on New Year’s Day in 1801.
Also in Egypt, spring was the time when festivals honoring the Apis-bull were held. It was also a time when the River Nile overflows its banks and brought water to the land, a time for planting to begin. At this time in history, roughly around 4000 B.C., the sun’s position along the Zodiac on the first day of spring or Vernal Equinox, was in the constellation we now recognized as Taurus, the Bull.
Taurus comprises two groups of stars called Pleiades and Hyades along with Crab Nebula.
The Pleiades, some 425 light years from Earth, form the shoulder of the Bull and its hundreds of stars are thought to have formed around 100 million years ago. Among many ancient civilization, the Pleiades were associated with agriculture on the fact that the stars appeared on the horizon around harvest time and Greek superstition cautioned sailors to set sail only during the months when the Pleiades were visible.
Hyades are one of the closest open star clusters that belong to Taurus constellation.
It forms head of the bull, Taurus. The stars which make up the Hyades are believed to be approximately, 400 million years old. The Hyades have been known since antiquity and the name itself dates back as far as 1000 B.C., when it was mentioned in various Greek sources. However, the Hyades was not recognized or classified as a cluster until the Twentieth Century.
Taurus marked the point of vernal equinox in the Chalcolithic and the Early Bronze Age (the "Age of Taurus"). The Pleiades were closest to the Sun at vernal equinox around the 23rd century BC. In Babylonian astronomy, the constellation was listed in the MUL.APIN as GU4.AN.NA, "The Heavenly Bull".
In essence, Taurus constellation may actually predate that of other constellations.
