Delphus
In Greek mythology, Delphus /ˈdɛlfəs/ or Delphos (Δέλφος) was the person from whom the town of Delphi was believed to have derived its name.
In one tradition, he was the son of Poseidon and Melantho, a daughter of Deucalion.
In other accounts he was a son of Apollo by Celaeno, the daughter of Hyamus and granddaughter of Lycorus, and, according to others, by Thyia, the daughter of the autochthon Castalius, or by Melaina, the daughter of Cephissus. He is further said to have had a son, Pythis, who ruled over the country about Mount Parnassus, and from whom the oracle received the name of Pytho.
