Ovid's Version, and the Modern Reading

Ovid's account is specific about the mechanics of the punishment: Athena does not kill or disfigure Medusa outright but transforms only her famously beautiful hair into serpents, leaving the rest of her form as it was, a detail that later readers have found makes the punishment feel especially pointed, since the very feature that had attracted Poseidon's assault becomes the instrument of Medusa's monstrous new appearance. The ancient apotropaic use of her face continued long after antiquity in its own right, independent of any narrative reading: Caravaggio's Medusa, painted around 1597 on a ceremonial shield exactly in the old gorgoneion tradition, shows the severed, still-screaming head at the instant of death, a Baroque return to the face's original function as a shield-image meant to shock rather than to symbolise female suffering.

Her name also travelled into modern science. Carl Linnaeus and later naturalists borrowed Medusa as the taxonomic term for the free-swimming, tentacled jellyfish form, medusa in the singular, a name drawn directly from the image of a head surrounded by writhing, snake-like strands, so that Medusa survives today as ordinary biological vocabulary almost entirely detached from either the ancient monster or the modern feminist reading of her story.
