Overview
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.
Silenus presides over other daimons and is related to musical creativity, prophetic ecstasy, drunken joy, drunken dances and gestures.
In the decorative arts, a "silene" is a Silenus-like figure, often a "mask" (face) alone.
Evolution
The original Silenus resembled a folkloric man of the forest, with the ears of a horse and sometimes also the tail and legs of a horse. The later sileni were drunken followers of Dionysus, usually bald and fat with thick lips and squat noses, and having the legs of a human. Later still, the plural "sileni" went out of use and the only references were to one individual named Silenus, the teacher and faithful companion of the wine-god Dionysus.
