Musaeus
A semi-mythological personage who was represented by one tradition to be the son of Orpheus. He is said to have written sacred poems and oracles. Milton couples his name with that of Orpheus in his "II Penseroso": "But O, sad virgin, that thy power Might raise Musaeus from his bower, Or bid the soul of Orpheus sing Such notes as warbled to the string, Drew iron tears down Pluto's cheek, And made Hell grant what love did seek."
