 Nephele, or her spirit, appeared to the children with a winged ram whose fleece was of gold.The ram had been sired by Poseidon in his primitive ram-form upon Theophane, a nymph and the granddaughter of Helios, the sun-god.According to Hyginus, Poseidon carried Theophane to an island where he made her into a ewe, so that he could have his way with her among the flocks.
