Hieroglyphics of Horapollo, tr. Alexander Turner Cory, , at sacred-texts.com
When they would symbolise one enemy engaging with another equal to himself, they depict a SCORPION AND A CROCODILE. For these kill one another. But if they would symbolise one who is hostile to, and has slain another, they depict a CROCODILE or a SCORPION; and if he has slain him speedily, they depict a CROCODILE, but if slowly, a SCORPION, from its tardy motion.
