Over the course of Greek history, satyrs gradually became portrayed as more human and less bestial. They also began to acquire goat-like characteristics in some depictions as a result of conflation with the Pans, plural forms of the god Pan with the legs and horns of goats. The Romans identified satyrs with their native nature spirits, fauns. Eventually the distinction between the two was lost entirely. Since the Renaissance, satyrs have been most often represented with the legs and horns of goats. Representations of satyrs cavorting with nymphs have been common in western art, with many famous artists creating works on the theme. Since the beginning of the twentieth century, satyrs have generally lost much of their characteristic obscenity, becoming more tame and domestic figures. They commonly appear in works of fantasy and children's literature, in which they are most often referred to as "fauns".
