illegal slave ships at sea, predominately after 1842. In 1823, the Society for the Mitigation and Gradual Abolition of Slavery Throughout the British Dominions (known as the first Anti-Slavery Society) was founded in Britain, dedicated to abolishing slavery throughout the British Empire; the Slavery Abolition Act 1833 represented the achievement of their goal. The Zong massacre was frequently cited in abolitionist literature in the 19th century; in 1839, Thomas Clarkson published his History of the Rise, Progress, and Accomplishment of the Abolition of the African Slave Trade, which included an account of killings. Clarkson's book had an important influence on the artist J. M. W. Turner, who displayed a painting at the Royal Academy summer exhibition in 1840 entitled The Slave Ship. The painting depicts a vessel from which a number of manacled slaves have been thrown into the sea, to be devoured by sharks. Some of the details in the painting, such as the shackles worn by the slaves, appear to have been influenced by the illustrations in Clarkson's book. The painting was shown at an important time in the movement to abolish slavery in the world, as the Royal Academy exhibition opened one month before the first World Anti-Slavery Convention in London. The painting was admired by its owner, John Ruskin. It has been described by the 20th-century critic Marcus Wood as one of the few truly great depictions in Western art of the Atlantic slave trade. Representations in modern culture The Zong massacre has inspired several works of literature. Fred D'Aguiar's novel Feeding the Ghosts (1997) tells the story of an African who survives being thrown overboard from the Zong. In the novel, the journal of the slave—Mintah—is lost, unlike that of Granville Sharp. According to the cultural historian Anita Rupprecht, this signifies the silencing of African voices about the massacre. Margaret Busby's play An African Cargo, staged in 2007 by Nitro theatre company at Greenwich Theatre and directed by Felix Cross, dealt with the massacre and the 1783 trials, making use of the original legal transcripts. M. NourbeSe Philip's 2008 book of poems Zong! is based on the events surrounding the massacre and uses the account of the King's Bench hearing as its primary material. Philip's text physically deconstructs the account as a method for undermining the document's authority. An episode of the television programme Garrow's Law (2010) is loosely based on the legal events arising
