(Previously, Pisces)
Ever hear of Jason and the Argonauts and the quest for the ram's golden fleece? Same Ram as the constellation Aries. As the story goes, young Phrixus was getting hit on by his auntie. When he declined her advances, she accused him of rape. Just as his father was (hesitantly) about to cut Phrixus's throat in sacrifice to Zeus, Hercules wandered by and stopped the execution. "Daddy don't dig on human sacrifices, yo," he allegedly said. At the same time, a ram with a golden fleece was sent to rescue Phrixus and his sister. The two humans hopped on board the ram and flew away. When they landed safely, the ram told Phrixus to sacrifice him (the ram) to Zeus, and take his golden fleece to the king. The king was well pleased with the gift and became Phrixus's foster father. Later on, Jason went after the fleece, but that's neither here nor there. In commemoration of the ram's selflessness, Zeus placed him in the sky as a constellation.
