Imamiah

Imamiah - In the cabala, an angel of the order of principalities, or rather an ex-angel of that order, since he is fallen.  In hell he supervises and controls voyages, and destroys and humiliates enemies, when he is invoked to do so, or is so disposed.  He was once one of the 72 angels that bore the name of God Shemhamphorae.  His sigil is pictured in Ambelain, La Kabbale Pratique, p. 289.  (a)
