Il Milione
Rustichello da Pisa, also known as Rusticiano (fl. late 13th century), was an Italian romance writer in Franco-Italian language. He is best known for co-writing Marco Polo's autobiography, "The Travels of Marco Polo", while they were in prison together in Genoa. Earlier, he wrote the "Roman de Roi Artus" ("Romance of King Arthur"), also known as the "Compilation", the earliest known Arthurian romance by an Italian author.
