Calvamia

Calvamia: A demon who serves beneath the King of the Northeast, Armadiel. Calvamia is a mighty duke, waited upon by eighty-four lesser spirits.

His name and seal both appear in the Ars Theurgia. Many of the demons described in this text are also tied to certain times of the day. In the case of Calvamia, if the day is divided into fifteen equal portions, Calvamia's portion is the fourth. He is bound to appear only during these hours.
