Aesacus
Aesacus or
Aisakos in
Greek mythology was a son of King
Priam of
Troy. Aesacus sorrowed for the death of his wife or would-be lover, a daughter of the river
Cebren, and was transformed into a bird.
Apollodorus (3.12.5) makes Aesacus son of Priam's first wife
Arisbe daughter of
Merops. Apollodorus and
Tzetzes (
Scholiast on Lycophron 224) also make Aesacus a seer who has learned the interpretation of dreams from his grandfather Merops. For them Aesacus is the interpreter of
Hecabe's dream when Hecabe gives birth to
Paris. In Apollodorus the deceased daughter of Cebren for whom Aesacus mourns is his wife named Asterope.
In
Ovid's
Metamorphoses (11.749-759), Aesacus is an illegitimate son of King Priam secretly born to the nymph Alexirhoe daughter of the river
Granicus. Aesacus avoids
Ilium, preferring the countryside. One day he catches sight of the nymph Hesperia daughter of the river
Cebren, falls in love, and pursues her. But as Hesperia flees a poisonous snake strikes her and she dies. Aesacus, unable to bear living any longer, leaps from a tall cliff into the sea but as he plunges he is changed into a bird by
Thetis. Aesacus still attempts to dive into the depth yet continues still to live in the form of a diving bird.
