Amphilochus I of Argos

Amphilochus is presented as the son of the seer-king Amphiaraus and Eriphyle and the younger brother of Alcmaeon; he belongs to the generation of the Epigoni (the sons who avenged their fathers after the failed expedition of the Seven against Thebes). Sources summarized in the supplied material credit him with kingship in Argos in some accounts and with post-Trojan War settlement activity that led to the naming of Amphilochia and a second 'Amphilochian Argos'. Ancient authors cited in the tradition include Herodotus (for a foundation at Posideium) and geographical writers like Strabo for the attribution of place-names; other mythographic sources (e.g., summaries of Apollodorusic material) place him among the Epigoni and record variant traditions that sometimes assign certain foundations or death-stories instead to a nephew. The tradition thus records multiple, sometimes conflicting, attributions for his civic and cultic foundations.

The supplied sources do not provide a physical or iconographic description of Amphilochus. Ancient summaries and modern reference accounts focus on his genealogy, political and cultic acts (founder, king, seer), and contested death-stories rather than bodily features; therefore no reliable depiction or standard iconography is attested in the provided material.

Amphilochus is primarily attested as a heroic seer and founder. Multiple summaries credit him with a reputation for prophetic ability (a trait inherited from his father Amphiaraus) and with founding oracles — most prominently an oracle at Mallus in Cilicia and, in some traditions, the oracle of Apollo at Colophon in Lydia (the latter said to be founded jointly with his half-brother Mopsus). He is also credited in post-Trojan War settlement legends with establishing territory along the Ambracian Gulf known as Amphilochia and an 'Amphilochian Argos', and Herodotus is reported to attribute the establishment of Posideium on the Cilician border to him. Traditions conflict over his death: some say he was killed by Apollo, others that he and Mopsus killed one another; alternative accounts ascribe those events to a nephew, indicating variation across sources.
