English: "Description of a slave ship," by an anonymous artist, wood engraving, 328 mm x 444 mm. "This is one of several prints produced from the same woodblocks showing plans and sections of the slave ship "Brookes" of Liverpool. A model of the ship was used by William Wilberforce in the House of Commons to demonstrate conditions on the Middle Passage. The woodcut was first produced in 1786 to illustrate various works by Thomas Clarkson, and was then distributed separately by abolitionists." Courtesy of the British Museum, London.
