What is the author's style in The Travels of Marco Polo by Marco Polo?

ustichello is a romance writer and fellow prisoner of war with Marco Polo in a Genoa prison during this period while they co-write the "Travels." Rustichello writes in French and some similarities between the narrator's tale of Tristan at King Arthur's Camelot and Marco Polo's tales at Kubilai's court are curious. Some other tales are common tradition like the three Magi and other Middle East legends. Rustichello's experience in romance writing makes "Travels" a best-seller according to the translator Latham. Ronald Latham wrote, edited and translated many works as a Fellow of the Society of Antiquaries before his death in 1992. Latham bases the "Travels" on Professor Benedetto who provides a "straightforward and readable version" but makes no claim to satisfy needs of specialists.
