Delphus was said to be the son of Poseidon and Melantho (Melantheia), daughter of Deucalion.
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.
[2] In yet another version, his mother is Melanis, a daughter of Hyamus and Melantheia, and father is not mentioned; Delphus is said to have inherited his grandfather's kingdom in the neighborhood of Mount Parnassus, to have married Castalia, and to have had two children, a son Castalius and a daughter Phemonoe, the first person to write hexameters.
