The Medusa was a French ship which ran aground off the coast of West Africa in 1816. Due to insufficient lifeboats a scheme was hatched for the lifeboats to tow a raft. The story is one of stupidity, incompetence, treachery and even cannibalism. I used part of a lobster creel for the raft and of course have seen Gericault’s painting of the same name in the Louvre.
