One of the first written accounts to mention constellations was the poem PhaenomenaWho wrote this poem?

Aratus of Soli in Cilicia, ca. 315-245 BCE, was a didactic poet at the court of Antigonus Gonatas of Macedonia, where he wrote his famous astronomical poem Phaenomena (Appearances). He was for a time in the court of Antiochus I of Syria but returned to Macedonia. Phaenomena was highly regarded in antiquity; it was translated into Latin by Cicero, Germanicus Caesar, and Avienus.

The earliest systematic account of the constellations is contained in the Phaenomena of Aratus who described 43 constellations and named five individual stars.
