Hieroglyphics of Horapollo, tr. Alexander Turner Cory, [1840], at sacred-texts.com
When they would denote a man who is fearful lest accidents should happen unexpectedly to himself, they depict a WOLF AND A STONE; for it fears neither iron, nor a stick, but a stone only; and indeed, if any one throw a stone at him he will find him terrified: and wherever a wolf is struck by a stone, maggots are engendered from the bruise.
