The weather spirit responsible for the south-westerly gales on the Firth of Cromarty. The Firth is well protected from the north and east, but a gap in the hills allows the entry of spasmodic squally gales. These gives Gentle Annis a bad reputation for treachery. A day will start fine and lure the fisher out, then, in a momemt, the storm sweeps round and his boat is imperilled. D. A. Mackenzie suggests that Gentle Annis is one aspect of the Cailleach Bheur. 'Annis' may come from the Celtic goddess Anu, which has been suggested, as the origins of Black Annis of the Dane Hills. It may be, however, that these half-jocular personifications have no connection with mythology.
