Iphinoe

Iphinoe does not have a single origin story. The name appears in multiple contexts in Greek mythic genealogies and narratives: as a daughter of King Proetus (one of the Proetids) who shares in the episode of divine-driven madness and subsequent purification by the seer Melampus; as a female herald on Lemnos who announces the arrival of the Argonauts to Queen Hypsipyle; and, in modern scientific nomenclature, as the eponym for a crustacean genus said to be named after a Greek nymph of the cave Kastria (the latter derived from a taxonomic note rather than an extant ancient narrative).

No consistent physical description is preserved across sources. In the Proetid tradition Iphinoe is treated as a mortal princess whose affliction involved public madness marked by stripping and wandering; some summaries report that in some versions Iphinoe died rather than being cured. In the Argonautic episode she appears as a functioning herald/announcer on Lemnos with no distinctive supernatural appearance recorded. The taxonomic note that names a nymph Iphinoe implies a local, place-associated female figure but gives no descriptive details.

Across attestations Iphinoe's roles are social and narrative rather than supernatural powers. As a Proetid she is a recipient of divine-induced madness and a subject of ritual purification (or, in some accounts, death) by the seer Melampus. As the Lemnian herald she functions communicatively—spotting the arriving Argonauts and informing Queen Hypsipyle. The modern taxonomic mention treats Iphinoe as the name of a cave-associated nymph but does not ascribe active powers in the supplied material.
