Earth-demons, called in Trulli Burton’s Anatomy of Melancholy. The word “trull” meaning a loose woman came from the same root ; thus the Troll was probably in the beginning the pagan hags or earth-priestesses.

In Norse folklore trolls were commonly described as sitting beneath bridges waiting to seize and eat those who did not give them an offering when crossing. This association with bridges suggests the Valkyaries who guarded the Bifrost, the Bridge of Heaven; they also were “trulls” or “trolls.” It was said the Angels of Death gathered at the divine Sabbat called the trolla-thing. A.G.H.
