 His accounts are contemporary, and fairly consistent with those of the Chinese writers who were on Zheng He's ships, such as Ma Huan (writing in 1433) and Fei Xin (writing in about 1436).After the return of Marco Polo in 1295, there is no record of Italian traders returning from China until the return of de' Conti by sea in 1439.However, we do have the account of the travels of a Franciscan friar by the name of Odoricus Mattiuzzi (1286-1331) from Friuli who in 1310 visited Armenia, Mesopotamia, Persia, Ceylon (Sri Lanka), Sumatra, Java, Cambodia, Champa and China.
