In Greek mythology, a satyr is a male companion of Dionysus with goat-like features and often permanent erection. In Roman Mythology there is a concept similar to satyrs, with goat-like features: the faun, being half-man, half-goat.
The satyr's chief was Silenus, a minor deity associated with fertility. They are lovers of wine and women, and they are ready for every physical pleasure. They roam to music, and they love to chase maenads or bacchants. Because of their love of wine, they are often represented holding wine cups, and they appear often in the decorations on wine cups.
