The name probably derives from "lume" or flame, due to the luminescence that would have been seen on summer nights above the cavity, produced by the gases generated by the putrefaction of animal carcasses thrown into the well. The cavity was formed by karst, or by the dissolution of the rock by water. According to legend, it is inhabited by the Anguane, very ugly fairies, with nails instead of hair, and long fangs instead of teeth. During the day they went to wash clothes at Lake Santa Croce, then wandered around in search of wood, food and children to roast. At night, they lit a small fire, whose light, spotted by shepherds, gives the cavity its name
