Hippalcimus

Hippalcimus appears in Greek mythic genealogies in two divergent traditions preserved in the sources. In one genealogical line he is given as son of Itonus (himself son of Boeotus) and as father, by Asterope, of Peneleos, which situates him in Boeotian lineage. In an alternative tradition recorded in heroic catalogues he is named as son of Pelops and Hippodamia, which places him within Peloponnesian noble descent. These differing filiations reflect a common feature of Greek myth where local genealogies and pan-Hellenic rosters preserve variant ancestries for the same named figure.

No physical description of Hippalcimus is preserved in the provided sources. He is attested only by name in genealogical lists and in the roster of the Argonauts; the extant notices do not include any portrayal of his stature, dress, or distinguishing features.

The surviving references do not ascribe supernatural powers, distinctive skills, or particular deeds to Hippalcimus. He functions in the sources primarily as a named node in genealogical networks (father of Peneleos in one account) and as a listed member of the Argonaut crew in catalogue tradition (Hyginus' list and summarized modern references). Major mythographers cited in the tradition (catalogues such as Hyginus' Fabulae and compendia summarized by modern reference works) record his name without individual exploits.
