Morpheus.
Morpheus, one of the sons of Hypnos (῞Υπνος, Lat. Somnus, Sleep), is the god of dreams, a simulator figurae. Though personified dreams (ὀνείροι) occur in literature since Homer, Morpheus makes only one specific appearance in classical literature, when Ovid has him impersonate the deceased Ceyx and appear to Alcyone, his widow. The name of Μορφεύς associates him with the various (but only human) shapes (morphai) the god can assume. Ovid mentions among Morpheus’ thousands of brothers only Icelus and Phantasus.
