The French frigate Méduse strikes the Bank of Arguin and 151 people on board have to be evacuated on an improvised raft, a case immortalised by Géricault's painting The Raft of the Medusa.

Méduse was a 40-gun Pallas-class frigate of the French Navy, launched in 1810. She took part in the Napoleonic Wars during the late stages of the Mauritius campaign of 1809–1811 and in raids in the Caribbean.

The Bay of Arguin is a bay on the Atlantic shore of Mauritania and the former mouth of the Tamanrasset River, now a Paleo-river.

Jean-Louis André Théodore Géricault was a French painter and lithographer, whose best-known painting is The Raft of the Medusa. Despite his short life, he was one of the pioneers of the Romantic movement.

The Raft of the Medusa – originally titled Scène de Naufrage – is an oil painting of 1818–1819 by the French Romantic painter and lithographer Théodore Géricault (1791–1824). Completed when the artist was 27, the work has become an icon of French Romanticism. At 491 by 716 cm, it is an over-life-size painting that depicts a moment from the aftermath of the wreck of the French naval frigate Méduse, which ran aground off the coast of today's Mauritania on 2 July 1816. On 5 July 1816, at least 150 people were set adrift on a hurriedly constructed raft; all but 15 died in the 13 days before their rescue, and those who survived endured starvation and dehydration and practiced cannibalism. The event became an international scandal, in part because its cause was widely attributed to the incompetence of the French captain. Géricault chose this large-scale uncommissioned work to launch his career, using a subject that had already generated widespread public interest. The event fascinated him.
