In Greek mythology, Silenus was a companion and tutor to the wine god Dionysus. He is typically older than the satyrs of the Dionysian retinue (thiasos), and sometimes considerably older, in which case he may be referred to as a Papposilenus. Silen and its plural sileni refer to the mythological figure as a type that is sometimes thought to be differentiated from a satyr by having the attributes of a horse rather than a goat, though usage of the two words is not consistent enough to permit a sharp distinction.

Cyclops is an ancient Greek satyr play by Euripides, based closely on an episode from the Odyssey. It would have been the fourth part of a tetralogy presented by Euripides in a dramatic festival in 5th Century BC Athens. The date of its composition is unknown, but it was probably written late in Euripides' career. It is the only complete satyr play extant.
