Take Me Back to Constantinople; Now it's Istanbul, Not Constantinople

Document 1: written by a Jewish rabbi named Benjamin of Tudela who is writing to the Jews. He writes about the glorious wonders of Constantinople but how the Jews are treated poorly.
Document 2: written by Robert of Clari to the general public about the riches and wonders of Constantinople and how when it was captured its captors were amazed by its wealth and beauty. The document talks about the many cathedrals maybe to suggest the importance of religion to the Byzantine Empire.
Document 3: written by Nicetas Choniates to the general public about how the Latins went into Constantinople and destroyed the art.
Document 4: The map is not very trustworthy because the scale is not credible and the buildings look block and too large. There are few cathedrals to show how religion was important. The land is surrounded by water and watch towers to illustrate how defensive they were and ready for attacks.
Document 5: The photo of the interior of Saint Sophia Cathedral shows the new type of art and architecture that was stirring in the Byzantine Empire.
Document 6: written by George Acropolites to the world and is a third-party narrative about the journey of the emperor Michael VIII Palaeologus. The emperor performed religious ceremonies and gave the patriarch the throne.
Document 7: written from a viewpoint of a citizen and talks about the great things the Venetians have done. It also talks about the special benefits and privileges the Venetians have. This document is not very trustworthy because it only mentions Constantinople for its trading port.

I think that Document 1 and 2 are the most credible documents because they both describe Constantinople in great detail from the wealth and riches to the cathedrals, even specific ones such as Saint Sophia. Many of the other documents do not discuss Constantinople in this much of detail or barely mentions it.
