Toro

Bulls:  This curiously named demon appears in the night-bound hierarchy of the infernal prince Dorochiel.  Given the style of most angel names (fallen or otherwise), this demon may have originally been Buells.  According to the Ars Theurgia, where his name appears, Bulls will only manifest at a specific hour in the first half of the night.  Through Dorochiel, he owes fealty to the court of the west.  Granted the rank of chief duke, he has forty lesser spirits under him.  See also ARS THEURGIA, DOROCHIEL.
