A prose comedy by Lyly, published 1584 under the title Alexander, Campaspe and Diogenes. Alexander the Great engages Apelles to paint the portrait of his Theban captive Campaspe. Apelles and Campaspe fall in love; when the portrait is finished he spoils it to occasion further sittings. Alexander becomes suspicious and by a trick makes Apelles reveal it. He surrenders Campaspe to Apelles and returns to his wars. The story is told in Pliny's Natural History, 35, 10.
