Æsculapius (Æscula`pius) , a son of Apollo and the nymph Coronis, whom, for restoring Hippolytus to life, Zeus, at the prayer of Pluto, destroyed with a thunderbolt, but afterwards admitted among the gods as god of medicine and the healing art; the cock, the emblem of vigilance, and the serpent, of prudence, were sacred to him.
