Campaspe is an Elizabethan era stage play, a prose comedy by John Lyly based on the story of the love triangle between Campaspe, a Theban captive, the artist Apelles, and Alexander the Great, who commissioned him to paint her portrait. Widely considered Lyly's earliest drama, Campaspe was an influence and a precedent for much that followed in English Renaissance drama, and was, according to F. S. Boas, "the first of the comedies with which John Lyly inaugurated the golden period of the Elizabethan theatre".[1]
