Greek sculptor, probably an Athenian. Leochares was associated in the decoration of the Mausoleum at Halicarnassus. He is known to have made portraits, including a gold and ivory group of Philip, Alexander, and others, for Olympia. His Lion Hunt of Alexander was made with Lysippos after 321 B.C. A copy of his Ganymede and the Eagle of Zeus is in the Vatican. The Apollo Belvedere (Vatican) is sometimes attributed to him, and the Diana of Versailles (Louvre), conceived as a companion piece, also reflects his style.
