his library containing many medieval manuscripts. Chronicle of the Conquest of Granada was published a year later, followed by Voyages and Discoveries of the Companions of Columbus in 1831. Irving's writings on Columbus are a mixture of history and fiction, a genre now called romantic history. Irving based them on extensive research in the Spanish archives, but also added imaginative elements aimed at sharpening the story. The first of these works is the source of the durable myth that medieval Europeans believed the Earth was flat. According to the popular book, Columbus proved the Earth was round.
