Apot
Apot: A demon who serves beneath Asmodeus and Magoth in the Mathers translation of the Sacred Magic of Abramelin the Mage. Mathers' source manuscript from fifteenth-century France is only one of two versions of the Abramelin material that contains this particular hierarchy. The other, a version from 1608 kept at the Wolfenbiittellibrary, gives a totally different spelling for this demon's name, to the point where it may well be a different demon entirely. The corresponding name in that text is Sochen.
