Margaret Alice Murray,
The Witch-Cult in Western Europe…
(1921)
“ The suggestion that the Devil was a man, wearing either an animal's skin or a mask in the form of an animal's head as a ritual disguise, accounts as nothing else can for the witches' evidence as to his appearance and his changes of form. A confusion, however, exists from the fact that the witches, and therefore the recorders, usually spoke of the familiars as the Devil; but in almost every case the disguised man can, on examination of the evidence, be distinguished from the animal familiar. ”
