Been a Long Time Gone, Constantinople

Document 1, written by Benjamin of Tudela, talks about the overview of Constantinople, describing it's wealth and beauty. This is a somewhat reliable source, but Benjamin was a Rabbi, so the religious aspects might have been off. It is pretty general though, so it was probably directed towards travelers or outsiders. Document 2 was written by Robert of Clari, and it discusses the immense wealth of Constantinople. The extent of said wealth might be exaggerated. It was directed towards the general public. Document 3 was about attacks on the city and were probably directed towards other citizens of Constantinople. Document 4 was a drawing of a map, which is only credible to a point. Considering the time period when it was drawn, it might not be accurate. Document 5 seemed the most credible to me, because it was an actual photograph. There isn't much room for bias in there. Document 6 once again discusses Constantinople's wealth, written by George Acropolites. It sounds credible enough, because he describes Constantinople realistically and it seems more factual. The last document was, again, about wealth and power. It's written by a historian, and it's directed towards the general public.
