A Dictionary of Greek and Roman biography and mythology

(Αἰγίπαν), that is, Goat-Pan, was according to some statements a being distinct from Pan, while others regard him as identical with Pan. His story appears to be altogether of late origin. According to Hyginus (Hyg. Fab. 155) he was the son of Zeus and a goat, or of Zeus and Aega, the wife of Pan, and was transferred to the stars. (Hygin. Poet. Astr. 2.13.28.) Others again make Aegipan the father of Pan, and state that he as well as his son was represented as half goat and half fish. (Eratosth. Catast. 27.) When Zeus in his contest with the Titans was deprived of the sinews of his hands and feet, Hermes and Aegipan secretly restored them to him and fitted them in their proper places. (Apollod. 1.6.3 ; Hygin. Poet. Astr. l.c.) According to a Roman tradition mentioned by Plutarch (Parallel. 22), Aegipan had sprung from the incestuous intercourse of Valeria of Tusculum and her father Valerius, and was considered only a different name for Silvanus.
