The Grand Grimoire refers to the demon Bael that Johan Weyer commences his inventory in the famous Pseudonomarchia Daemonum.

Weyer called this demon the first monarch of Hell, and head of all infernal powers, with his estates being in the Easter regions. He has three heads, a crap, a cat, and a human. He controls sixty-six legions that obey him. A.G.H.
