Alcmeonis

The Alcmeonis is not a mythic agent but the conventional title of an early Greek epic poem focused on the figure Alcmaeon. Ancient testimonia place it within the corpus of Theban epic (the Theban Cycle), where it functioned as one of the regional narratives that preserved Theban legendary history. In surviving ancient literature the poem is repeatedly cited as having an unknown author; modern summaries note that there are only a very small number of references (commonly given as seven) to the work in antiquity. Its principal narrative concern, as attested in the sources, is Alcmaeon's matricide of Eriphyle in retribution for her role in the death of Amphiaraus, a story whose wider context is also treated in other Theban epics such as the Thebaid.

As a text the Alcmeonis survives only in fragmentary citations in later ancient authors rather than as a complete manuscript. No single continuous copy of the poem is extant; the tradition preserves a small number of references (often summarized as seven ancient mentions) and at least one quoted fragment. Athenaeus preserves a fragment in his Deipnosophistae chosen because it describes a funeral banquet; commentators note that the fragmentary lines differ in character from Homeric feast-descriptions. Beyond these sparse quotations, the poem's full content and form remain lost to us.

The Alcmeonis has no supernatural abilities; treated as a literary poem, its operative role is narrative and cultural: to recount and transmit the mythic events surrounding Alcmaeon, especially the matricide of Eriphyle in vengeance for Amphiaraus. Functionally within the epic-cycle framework, the poem contributed to the mapping of heroic genealogy, causation, and moral consequences in Theban legendary history and preserved particular scenes of social practice (for example, a funeral banquet) that ancient readers found distinctive relative to Homeric models.
