The Travels of Marco Polo

The Travels of Marco Polo was a book written by Marco Polo, obtained by Ezio Auditore da Firenze in the 16th century in Constantinople.

Summary
''One of the most famous and widely read tracts of the 14th century, this travelogue paints a vivid and detailed portrait of explorer Marco Polo's twenty-year journey through the Orient. Brimming with tall tails and fantastical descriptions, its veracity remains a source of much controversy.''
