It is to be observed that the chief seat of Lycanthropy was Arcadia, and it has been very plausibly suggested that the cause might he traced to the following circumstance:–The natives were a pastoral people, and would consequently suffer very severely from the attacks and depredations of wolves. They would naturally institute a sacrifice to obtain deliverance from this pest, and security for their flocks. This sacrifice consisted in the offering of a child, and it was instituted by Lycaon. From the circumstance of the sacrifice being human, and from the peculiarity of the name of its originator, rose the myth.
