[FAMILY.FTW]
AETHUSA was a daughter of Poseidon and the Pleiad Alcyone, and sister of Hyrieus, Hyperenor, Hyperes, and Anthas. Hyperes and Anthas were kings of Troezen, probably concurrently, and had neighboring towns named for them. Hyrieus was the founder of Hyria in Boeotia and father of Orion. Aethusa was loved by Apollo and became by him the mother of Eleuther. According to one account, she was also mother by him of Linus, but most accounts call his mother Psamathe. Eleuther grew up to found Eleutherae in Boeotia. He is credited with having erected the first staue of Dionysus and with spreading the worship of the god. His grandson Poemander--and thus Aethusa's great-grandson--founded Tanagra. [Apollodorus 3.10.1; Pausanias 9.20.2.]
