What is "aethlius"

Aethlius was, in Greek mythology, the first king of Elis, father of Endymion. He was the son of Zeus and Protogeneia (daughter of Deucalion), and was married to Calyce. He led Aeolians from Thessaly and founded Elis. According to some accounts, Endymion was himself a son of Zeus and first king of Elis. Other traditions again made Aethlius a son of Aeolus, who was called by the name of Zeus.

Aethlius ( Ancient Greek: ) of Samos was the author of a work titled Samian Annals , the fifth book of which is quoted by Athenaeus, although he expresses a doubt about the genuineness of the work. Aethlius is also referred to by Clement of Alexandria, Eustathius, and in the Etymologicum Magnum. His date is uncertain, but it is probable he lived some time in the 5th or 6th century.
