Hey Constantinople, you forgot your documents..

Document 1 is from Benjamin of Tudela, a Rabbi, who pretty much gives an overview of the city, Constantinople. May be the document is just giving an overview information about the city to the others. Since Benjamin was a Rabbi, he talks about the places of worship and about the king - King Manuel.
Document 2 is from Robert of Clari, who talks about how the city was conquered and taken over. He also talks about pilgrims reacting to the city. Robert describes the different parts of the city. I think this document was written for the public in general - describing more of the city.

Document 3 is from Nicetas Choniates and talks about the statue of Hercules, and the barbarians. Technically, the barbarians did not like the beauty of the city and 'did not neglect to overturn the statues standing in the Hippodrome or any other marvelous works". I think this document talks about the history of the city to teach others.
Document 4 is the map of Constantinople - painted map from the 13th century. Since it was painted, I think it was created by some famous artist in the city. May be it was painted for the travelers or merchants who were travelling all the times just to guide them about the city.
Document 5 is a photograph of an Interior of a church - Saint Sophia. I think this was photographed to promote the culture, may be religion! It has to be taken by a modern photographer because there weren't cameras back in days.
Document 6 is from George Acropolites, who may be have been a servant of the emperor since the document mostly focuses on the emperor. I think the document was written for the people to get more knowledge of the king, especially the citizens of the city.
Document 7 is from Chrysobull Detailing, who might have been a historian since it gives information. Even though the document does not seem so real and factual, I think it was directed towards the people in general.
