The tragedy "Sardanapalus" by George Gordon Byron published in 1821 and produced in 1834 is set in Assyria, 640 B.C., under King Sardanapalus. The play deals with the revolt against the extravagant king and his relationship to his favourite slave Myrrha. Myrrha made Sardanapalus appear at the head of his armies, but after winning three successive battles in this way he was eventually defeated. A beaten man, Myrrha persuaded Sardanapalus to place himself on a funeral pyre which she would ignite and subsequently leap onto - burning them both alive. The play has been interpreted as an autobiography, with Sardanapalus as Byron's alter ego, Zarina as Byron's wife Anne Isabella, and Myrrha as his mistress Teresa. At a more abstract level Myrrha is the desire for freedom driving those who feel trapped or bound, as well as being the incarnation of Byron's dream of romantic love.
