Constantinople Documents

I found that document 1 is the most credible due to all of the information it gives. It was written by Rabbi Benjamin of Tudela for people that were visiting Constantinople. Document 2 was written by Robert of Clari in an attempt to attract people to Constantinople by glorifying it. Document 3 was written by Nicetas Choniates who described the Latins as barbarians for destroying artwork in Constantinople. Document 4 is by an artist that can not be identified and seems too simple of a map to be valid. Document 5 is also by an unknown photographer and it shows the importance of church to people of Constantinople. Document 6 is by George Acropolites for people later in history promoting religion and prayer. Document 7 is by Chrysobull and is an informative document to the public about how the Venetians have helped the people of Constantinople.
