One of Turner’s most celebrated works, Slave Ship is a striking example of the artist’s fascination with violence, both human and elemental. The painting was based on a poem that described a slave ship caught in a typhoon, and on the true story of the slave ship Zong whose captain, in 1781, had thrown overboard sick and dying slaves so that he could collect insurance money available only for slaves “lost at sea.” Turner captures the horror of the event and terrifying grandeur of nature through hot, churning color and light that merge sea and sky. The critic John Ruskin, the first owner of Slave Ship, wrote, “If I were reduced to rest Turner’s immortality upon any single work, I should choose this.”
