Antianeira of Argos

Antianeira is cited in Greek epic catalogue material as the mother of Idmon, an Argonaut. In the Orphic Argonautica she is named explicitly as the woman by whom Apollo fathered Idmon, the passage locating his birth 'on the river Amphryssos.' Alternate traditions exist: a scholiast on Apollonius Rhodius records a variant naming Asteria as Idmon's mother, indicating competing local or poetic genealogies rather than a single authoritative origin story.

The surviving sources provide no physical or iconographic description of Antianeira beyond identifying her as a woman of Argos. She appears in catalogue and genealogical lines as an Argive mother-name; no clothing, attributes, or portraiture are preserved in the cited passages. Later name-lists and compendia sometimes record the name 'Antianeira' among other female names or epithets, but those usages are fragmentary and not corroborated by the primary Argonautica lines that identify her maternally.

No supernatural powers, cult, or recurring mythic deeds are attributed to Antianeira in the provided sources. Her role in the extant material is strictly genealogical: she is named as the mother of Idmon in some traditions (notably the Orphic Argonautica, which pairs her maternity with Apollo's paternity). Beyond this filial attribution, the excerpted texts do not ascribe agency, magical abilities, or heroic exploits to her.
