Mormo

Mormo is one of the great frightening names of Greek antiquity — the terrible one, whose collective plural, the mormolykeia or terrible wolves, supplied the ancient world's general word for bugbears. The lore the compendia preserve is grisly: in her true form the mormo is covered in her own blood and blisters — though the tradition allows she is not so hideous as her kin the empousa — and she is a shape-shifter of legendary range, credited with a thousand horrid forms as well as one lovely one, the beautiful young woman with which she lures young men to be drained and eaten. When men are wanting, the tradition says plainly, she settles for the old and the young.

One ancient explanation gives the monster a biography: Mormo was a queen of the Laestrygonians, the cannibal giants of the Odyssey's coast, who lost her own children and now, bereaved and envious, kills the children of others. Whatever her origin, her working life in antiquity was domestic — she was the name nurses and mothers invoked to keep children in line, the threat that something would come in the night and bite the disobedient. In that nursery office she passed from Greece to Rome and far outlived her own monstrosity, dwindling from vampire to bogey while keeping the same name.

The name itself proliferated as fright-words do: the old collections record mormolikeion, mormoliki, mormolix, and other regional shapes, all recognizably the same syllables of alarm. Between the shape-shifting, the name-shifting, and the long descent from vampire to admonition, Mormo is less a fixed being than a two-and-a-half-thousand-year-old way of saying that the dark has teeth — and the philosophers made her generic name do exactly that work, using mormolykeion as their standing word for an empty terror. The census records her at both scales, monster and byword at once.

The paragraphs below are extrapolated; no source supports them.

Mormo reads as grief soured into appetite — if the bereaved-queen account is kept in view, her child-taking is the arithmetic of loss made monstrous, envy with a body count. The shape-shifting suggests a self long since dissolved: a thousand forms and none of them her own. What remains constant is the hunger for what she lost and the theater of fright that even Roman nurseries could domesticate. Read from her tradition, and marked as the speculation it is.
