Silenus  (si-lē´nus ).—A name specially applied to a satyr (q.v.) who brought up and instructed Bacchus and was his constant companion. He is described as a bald-headed, jovial old man, generally intoxicated, and hence unable to trust his own legs to carry him safely. He generally rode on an ass. He possessed prophetic powers, which he could be made to exercise by surrounding him with chains of flowers while he was drunk and asleep.
