Il Milione
Unlike many other nautical charts, the Catalan Atlas is read with the north at the bottom. As a result of this the maps are oriented from left to right, from the Far East to the Atlantic. The first two leaves, forming the oriental portion of the Catalan Atlas, illustrate numerous religious references as well as a synthesis of medieval mappae mundi (Jerusalem located close to the centre) and the travel literature of the time, notably "The Travels of Marco Polo" and the "Travels" of Sir John Mandeville. Many Indian and Chinese cities can be identified.
