Dames Blanches

The dames blanches, the White Ladies, are a kind of fee of Norman tradition, and the collectors class them among the less benevolent of the French fairy women. Their habit is architectural: they lurk at exactly the narrow places a traveler cannot avoid — ravines, fords, bridges, sunken lanes — and there present themselves and require something. The demand is small and ceremonial: that the passerby join the lady in a dance, or hand her across a plank. Whoever obliges is rewarded with courtesies — she makes her bows and vanishes — and passes unharmed.

Refusal is what shows what they are. The recorded exemplar is La Dame d'Aprigny, who kept a winding ravine on the ground of a later street of Bayeux: she barred passage with her turning dances, held out her hand, and if a man joined her she released him after a round or two — but if he drew back she seized him and flung him into the briar-filled ditches beside the way. The trial is pure etiquette; the penalty is thorns. Other tales of the kind attach other ladies to other bridges and fords of Normandy on the same terms.

The name travels beyond Normandy, and the tradition splits when it does. Elsewhere in France, spirits called dames blanches are death-warning apparitions attached to particular old families, kin to the Breton spirits called bandrhudes and, further out, to the Irish banshee. The older collectors are careful to add that neither sort should be confused with the white ladies of Teutonic tradition, who are spirits of a different order — treasure-keeping, castle-bound, and unconnected with the Norman toll of courtesy.

The paragraphs below are extrapolated; no source supports them.

The dames blanches read as courtesy made into a predator's rule. Everything recorded about them is transactional — a dance, a plank, a bow — and the violence is reserved entirely for those who decline the transaction, which suggests beings whose deepest concern is acknowledgment. They do not want the traveler's goods or life; they want the gesture. Formal, vain, exacting, and dangerous precisely in proportion to how little they ask. Read from the shape of their toll, and marked as speculation.
