Who helped Marco Polo write down the story of his travels in prison?

While Marco Polo was imprisoned, he dictated the account of his travels to Rustichello da Pisa, a writer who helped shape the narrative.1

Although the work is known as the Travels of Marco Polo or Il milione, Rustichello asserted his own personality and familiar literary style into the text, particularly in his descriptions of battles. Because there is no surviving original manuscript, the history of the book remains complex, with many later versions influenced by various scribes, translators, and editors who often altered the content.21
