Centaurus

IAU star chart (CC By: IAU and Sky & Telescope magazine, Roger Sinnott & Rick Fienberg)

One of the 88 IAU constellations. The ancient Greek constellation of the Centaur forms a super-constellation with Lupus and Ara. It is unknown whether or not Centaurus had a Babylonian predecessor: The Mesopotamian uranologies in this area mention a god (Numushda) whose appearance and exact location in the sky are not preserved, and the constellation UR.IDIM which is commonly translated as "Mad Dog" (or rabid dog) but also associated with a benevolent door keeper daemon who is a lion-man. Such a lion-man may possibly be depicted in seal imprints and mythologically named Urmahlullu.

Etymology and History

The Greek constellation is possibly derived from a Babylonian one. There were several centaur-like creatures and other mixed man-animal beings in Mesopotamian culture; seal imprints and reliefs witness them.

Origin of Constellation

Greco-Roman

Aratos

[400] This cluster as a whole men call The Water. But others low beneath the forefeet of the Archer (Centaur) [Centaurus], a tuned in a circled ring, go wheeling round the sky.

[436] The constellation of Centaur [Centaurus] thou wilt find beneath two others. For part in human form lies beneath Scorpio, but the rest, a horse’s trunk and tail, are beneath the Claws. He ever seems to stretch his right hand towards the round Altar, but though his hand is drawn and firmly grasped another sign – the Beast [Fera], for so men of old have named it.

[660?] So she is borne towards the West, but other signs in the East the vault of heaven brings from below, the remaining half of the Crown and the tail of the Hydra, and uplifts the body and head of the Centaur and the Beast that the Centaur holds in his right hand. But the fore-feet of the Centaur-Knight await the rising of the Bow.

[694] But opposite the Horse starry Night draws the Centaur, tail-first, beneath the horizon, but cannot yet engulf his head and his broad shoulders, breast and all. (Kidd 1997)

Eratosthenes
Hipparchus
Hyginus, Astronomica

He is said to be Chiron, son of Saturn and Philyra, who surpassed not only the other Centaurs but also men in justice, and is thought to have reared Aesculapius and Achilles. By his conscientiousness and diligence, therefore, he won inclusion among the stars.

When Hercules was once visiting Chiron, and while sitting with him was examining his arrows, one of them is said to have fallen on the foot of Chiron, and thus brought about his death. Others say that when the Centaur wondered at his being able to kill such huge creatures as Centaurs with such slight arrows, he himself tried to draw the bow, and the arrow, slipping from his hand, fell on his foot. For this reason Jupiter, pitying him, put him among the constellations with a victim which he seems to hold above the altar for sacrifice.

Others have said that he is Pholus the Centaurus, who was more skilled in augury that the rest. Consequently, by the will of Jove, he was represented coming to the altar with a victim. (Mary Ward 1960)
