ANDROCLUS, a Roman slave who used to lead about the streets a lion which had forbore to injure him when turned loose in the circus. The story is related, on the authority of an eye-witness, by Aulus Gellius (v. 14), who states that Androclus had taken refuge from the severities of his master in a cave in Africa, and that while there, a lion entered the cave and presented to him his swollen paw, from which Androclus extracted a large thorn.
