Euryanassa

Euryanassa is attested in multiple, variant genealogical traditions. In one tradition she is named as daughter of the river-god Pactolus (Paktolos) and as the wife of Tantalus, listed among possible mothers of Pelops, Broteas, and Niobe. In an alternate tradition she is recorded as daughter of Hyperphas, leader of the Phlegyans, and as mother of Minyas by Poseidon, making her sister to Euryganeia in that lineage. The attestations are primarily genealogical listings and epithet-lists rather than narrative birth myths; the name also appears as a surname/epithet of the goddess Hebe in at least one source listing.

No ancient primary source supplied a physical or iconographic description of Euryanassa. Surviving attestations treat her as a named wife and mother within genealogical accounts rather than as a figure described in visual or corporeal detail.

Sources do not attribute supernatural powers, cult functions, or independent mythic deeds to Euryanassa. Her role in the tradition is familial and genealogical: she is named as spouse and mother in competing local traditions that locate major heroic lineages. Where she is called daughter of a river-god, that filiational link implies semi-divine ancestry (as with other naiad/river-descended figures), but the attestations do not narrate any powers or actions for her.
