 According to Ovid, two of his brothers were Morpheus, who appeared in dreams in human form, and one called Icelos ('Like'), by the gods, but Phobetor ('Frightener') by men, who appeared in dreams in the form of beasts.The three brothers' names are found nowhere earlier than Ovid, and are perhaps Ovidian inventions.Tripp calls these three figures "literary, not mythical concepts".
