Delphus

In the mythographic accounts collated by modern summaries and reference works, Delphus functions as an eponymous founder whose name explains the place-name Delphi/Delphos. The traditions are variant: one line names him son of Poseidon and Melantho (Melantheia), daughter of Deucalion; other accounts name Apollo as his father, with mothers given variously as Celaeno (daughter of Hyamus and granddaughter of Lycorus), Thyia (daughter of Castalius), or Melaina (daughter of Cephissus). In another recension his mother is Melanis (daughter of Hyamus and Melantheia) and no father is specified; in that version he inherits his grandfather's kingdom around Mount Parnassus, marries Castalia, and fathers Castalius and Phemonoe. He is also reported as father of Pythis, from whom the oracle's older place-name Pytho was said to derive. The sources present these alternatives rather than a single canonical genealogy, using Delphus as an etiological ancestor linking divine lineage, local rulership, and the Delphic oracle.

The surveyed sources offer no physical or iconographic description of Delphus. He is represented in the material as a genealogical and eponymous figure—named in parentage and offspring lists—rather than as a described visual or cult statue subject. No primary or secondary accounts in the provided materials record depictions, attributes, or a cult image explicitly associated with Delphus.

Delphus is not credited in the consulted accounts with discrete supernatural powers, prophetic functions, or recurring interventions in mythic narratives. His role is etiological and genealogical: by being named as son, husband, or father of other figures, he establishes lines of descent that link the locality of Delphi to divine or semi-divine origins (Poseidon or Apollo) and to figures associated with the oracle (Pythis, Phemonoe). The sources thus treat him as a foundational ancestor rather than as an active bearer of magical abilities.
