Aesacus

Aesacus was a Greek mythological figure, son of Priamus and the nymph Alexirrhoe (or alternatively Arisbe), who fell in love with Hesperia. She fled from him but was bitten by a snake and died. Aesacus, grieving, attempted to drown himself but was changed into a bird by Tethys.

Ovid XI, 749-759.
