King Arthur
Geoffrey of Monmouth wrote the first book about Arthur in the 12th century.  In the 15th century, Sir Thomas Malory wrote one of the best-known books about Arthur, called Le Morte d’Arthur (The Death of Arthur).  Later, in the 19th century, Alfred, Lord Tennyson visited Tintagel, the mythical Camelot, twice.  He wrote a series of poems about Arthur.
