Amandiel's name may be an intentional variation of Amenadiel, showing his fealty to this greater scion of Hell. Through his association with Amenadiel, Amandiel is connected with the west.
Although the Ars Theurgia offers little on the origin or significance of his name, it does tell us that Amandiel is a demon connected with the hours of the day. He holds that rank of chief duke and has thirty lesser spirits to serve him. He excels at hiding away treasures so they may not be stolen, and he can also reveal treasure hidden away through magickal means.
