Ipes/Ipos

Ipos - Dictionnaire Infernal

Dictionnaire Infernal – Collin de Plancy (1863) (paraphrased)
Ipes/ Ayperos is a prince and count of hell, who commands 36 legions. He appears as an angel or lion with the head and feet of a goose and a short hair’s tail. Ipes knows of the past and future, gives men intellect and courage, and can tell of hidden treasures.

Pseudomonarchia daemonum – Johann Wier (1583) (quoted)

Ipos (Ipes), alias Ayporos (Ayperos), is a great earle and a prince, appeering in the shape of an angell, and yet indeed more obscure and filthie than a lion, with a lions head, a gooses feet, and a hares taile: he knoweth things to come and past, he maketh a man wittie, and bold, and hath under his jurisdiction thirtie six legions.

Goetia – S. L. MacGregor Mathers (1904) (quoted)
