Prymno (Πρυμνώ)

Prymno is listed among the Oceanids, the many daughters of the Titans Oceanus and Tethys. The Oceanids are a large class of named female water-nymphs in Greek myth (the sources give their number as three thousand). Prymno's primary attestation is as one name within Hesiodic-type Oceanid name-lists; beyond parentage and inclusion among the Oceanids, no narrative origin or deeds are recorded in the provided materials.

No described iconography or physical description for Prymno survives in the supplied sources; she appears only as a name in Oceanid lists. The etymological glosses attached to her name — rendered as "undermost, root" and compared to a "cascade which falls down over a great height" — suggest symbolic imagery of downward motion or the lowermost part of something (an association later summarized as an affinity with a ship's stern), but such imagery is interpretive and not attested as a historical depiction.

The provided sources do not record any specific acts, powers, or behaviors for Prymno. By classification she belongs to the general category of Oceanids — water-associated nymphs and personifications of particular waters or water-related functions — so she may be understood within that broad conceptual role; however, no unique or attested abilities, ministrations, or myths for Prymno are present in the cited material.
