Matthew Barney's art video "Drawing Restraint 7" (1993) includes two satyrs wrestling in the backseat of a moving limousine. A satyr named Grover Underwood appears in the young adult fantasy novel "The Lightning Thief" (2005) by American author Rick Riordan, as well as in subsequent novels in the series "Percy Jackson & the Olympians". Though consistently referred to as a "satyr", Grover is described as having goat legs, pointed ears, and horns. Grover is not portrayed with the sexually obscene traits that characterized classical Greek satyrs. Instead, he is the loyal protector to the main character Percy Jackson, who is the son of a mortal woman and the god Poseidon.
