Richard Payne Knight's first book was about the Worship of this deity, who was said to be born in the city of Lampsacus on the Hellespont. A wall painting in the House of the Vettii in Pompeii depicts this god weighing various fruits against one of his own possessions. In a pair of stories from Ovid's Fasti, the braying of a donkey belonging to Silenus foiled this god's attempt to rape either the nymph Lotis or Vesta. This son of Dionysus and Aphrodite served as a patron god for merchant sailors, while red-painted statues of him were placed in fields to serve as simultaneous scarecrows and fertility emblems.
