Sgr star chart (IAU and Sky & Telescope magazine, Roger Sinnott & Rick Fienberg).

One of the 88 IAU constellations. Originally, it depicted the Mesopotamian god Pabilsaĝ, a god of agriculture and war, later equated with Ninurta and depicted as a mixed creature of a human body attaced to horse body with wings and an additional scorpion tail. This complex image was simplified in Greek reception, and there drawn as a centaur.

Origin of Constellation

Greco-Roman

Aratus

[300] After much suffering at sea even in the previous month, when the sun inflames the bow and the Drawer of the bow, you should put ashore in the evening and not continue to trust the night. A sign of that season and that month will be the rising of the Scorpion at the end of night. [305] The Archer actually draws his great bow near the sting; the rising Scorpion stands a little ahead of him, and he then rises shortly after. At that time the head of Cynosura runs very high up at the end of night, and just before dawn Orion sets entirely, and Cepheus from hand to waist. (Kidd 1997)

Hyginus, Astronomica

Many have called this sign the Centaurus; others deny the name, for the reason that no Centaurus makes use of arrows. The question is raised, too why he is formed with horse flanks but a Satyr's tail. Some say that he is Crotus, son of Eupheme, nurse of the Muses. As Sositheus, writer of tragedies, says, he had his home on Mount Helicon and took his pleasure in the company of the Muses, sometimes even following the pursuit of hunting. He attained great fame for his diligence, for he was very swift in the woods, and clever in the arts. As a reward for his zeal the Muses asked Jove to represent him in some star group, and Jove did so. Since he wished to display all his skills in one body, he gave him horse flanks because he rode a great deal. He added arrows, since these would show both his keenness and his swiftness, and he gave him a Satyr's tail because the Muses took no less pleasure in Crotus than Liber did in the Satyrs. Before his feet are a few stars arranged in a circle, which some said were a wreath, thrown off as by one at play. (Mary Ward 1960)
