Princess Dahut is transformed into a weather mermaid

Princess Dahut is the legendary figure of Breton mythology associated with the city of Ys. In April 1888, the collector Hyacinthe Le Carguet documented her survival in the form of a mermaid called Marie Morgane. She supposedly haunts the waters near Tévenec with long blonde hair and a fish tail, and her appearance announces an imminent squall.
