Maskim

Maskim - in Akkadian religion the maskim are the 7 great princes of Hell, otherwise known as the 7 spirits of the abyss, of whom it was said that "although their seat is in the depths of the earth, yet their voice resounds on the heights," and that they "reside at will in the immensity of space."  Mephistopheles is one of the 7.  [Rf. Lenormant, Chaldean Magic;  Agrippa's Electors; and Conybeare's listing of the underworld planetary rulers in The Testament of Solomon.] (a)
