Mazeppa is a narrative poem written by the English romantic poet Lord Byron in 1819. It is based on a popular legend about the early life of Ivan Mazepa (1639-1709), a Ukrainian gentleman who later became Hetman of the Ukrainian Cossacks. According to the poem, the young Mazeppa has a love affair with a Countess Theresa while serving as a page at the Court of King John II Casimir Vasa. Countess Theresa was married to a much older Count. On discovering the affair, the Count punishes Mazeppa by tying him naked to a wild horse and setting the horse loose. The bulk of the poem describes the traumatic journey of the hero strapped to the horse. The poem has been praised for its "vigor of style and its sharp realization of the feelings of suffering and endurance". This poem also inspired Alexander Pushkin to write his poem Poltava as an answer to Byron's poem. Published within the same covers with "Mazeppa" was the short story "A Fragment", also known as "Fragment of a Novel" and "The Burial: A Fragment", one of the earliest vampire stories in English.
