Amphithemis

In the classical genealogical tradition Amphithemis is presented as the son of Apollo and Acacallis (daughter of Minos). Exiled or borne in Libya — the place to which Acacallis had been sent in these accounts — he functions as a founder or eponymous ancestor: Apollonius of Rhodes names him Garamas, connecting him to the Garamantes, and he is father by the Libyan lake-nymph Tritonis of two sons, Nasamon and Caphaurus (Cephalion). In a separate, later poetic reworking (Nonnus' Dionysiaca, 5th century AD) the same name is applied to a centaur, assimilating the name into the troupe of half-horse creatures that accompany Dionysus.

In the Hellenistic and mythographic sources that treat Amphithemis as Apollo's son he is not given a detailed physical description and is treated as a human or semi-divine ancestor in genealogical lists. In Nonnus' Dionysiaca Amphithemis is explicitly called a centaur — a half-human, half-horse being — though the provided summaries do not quote extended descriptive passages from Nonnus beyond this categorical identification.

As an eponymous progenitor in Apollonius/Hyginus-style accounts Amphithemis' role is genealogical and foundational rather than demonstrably miraculous: he begets offspring who serve as local eponyms and actors within heroic cycles (notably his son Caphaurus/Cephalion, a shepherd who kills two Argonauts after they plunder his flocks). The extant summaries attribute no specific supernatural feats to Amphithemis himself. The centaur-identification in Nonnus places him within the conventional behavioral field of centaurs in Greek poetry — martial strength, pastoral association, and participation in Dionysian retinues — but the supplied materials do not record individual exploits or powers for Amphithemis beyond that taxonomic placement.
