Dictionnaire Infernal
According to Rudd, Gamigin is opposed by the Shemhamphorasch angel Ieuiah. The "Pseudomonarchia Daemonum", Thomas Rudd's variant of the "Ars Goetia", and the "Dictionnaire Infernal" go into more detail than the "Lesser Key", with Gamigin forcing the souls of those who drowned into "airy bodies" to answer questions in either, with Weyer and de Plancy further claiming that Gamigan can do likewise for souls "which dwell in purgatorie (which is called Cartagra, that is, affliction of soules)".
