Capella, he writes, may represent Amalthea, a female goat said to have sustained the young Jupiter with her milk during his stay on the island of Crete, where Ops, his mother, had hidden him from his cruel father, Saturn. Another possibility is suggested by Richard Hinkley Allen, author of Star Names, Their Lore and Meaning. He too notes that Capella in some star tales represents the goat Amalthea.
