Aratus

[225] There too are the most swift courses of the Ram [Aries], who, pursued through the longest circuit, runs not a whit slower than the Bear Cynosura – himself weak and starless as on a moonlit night, but yet by the belt of Andromeda thou canst trace him out. For a little below her is he set. Midway he treads the mighty heavens, where wheel the tips of the Scorpion’s Claws and the Belt of Orion. [239] Still father in front of the Ram and still in the vestibule of the South are the Fishes [Pisces]. [709] Her [Andromeda’s] right side the Fishes bring, but the left the rising Ram. When the latter rises, the Altar is seen setting in the West, [712] As to his belt itself disputed might it be whether it rises as the Ram ceases to rise or at the rising of the Bull [Taurus], with whom he rises wholly.

Pseudo-Eratosthenes

this ram carried Phrixos and Helle, son and daughter of the king Athamas of Böotia, from their home across the sea. Helle was dropped into the sea and became pregnant from god Poseidon while Phrixos was braught to king Aietes. The ram had a golden skin and lived forever but droped of his gold for Phrixos and went to the stars.
