Note 128
If the satyr was the orang-outang, the great human ape (Buffon, Hist. Nat. tom. xiv. p. 43, etc.), one of that species might actually be shown alive at Alexandria in the reign of Constantine. Yet some difficulty will still remain about the conversation which St. Anthony held with one of these pious savages in the desert of Thebais (Jerom. in Vit. Paul. Eremit. tom. i. p. 238).
