Philaster, romantic tragicomedy by Francis Beaumont and John Fletcher, produced about 1608–10. The play solidified their joint literary reputation.
The drama’s title character is the legitimate heir to the throne of Sicily. He and Arethusa, daughter of the usurper to the throne, are in love, but she is to be married to Pharamond, a lecherous Spanish prince. When Arethusa exposes Pharamond’s excesses, the engagement is broken, and she is falsely accused of having an affair with her page, Bellario, formerly Philaster’s page. Convinced of this, Philaster angrily wounds Arethusa. Bellario, however, is actually Euphrasia, a young woman who is in love with Philaster. At the end, Bellario reveals her true identity, and Arethusa and Philaster reconcile. The usurper, fearing a popular uprising, restores Philaster to his throne and returns his lands.
