Count Robert of Paris

Count Robert of Paris (1832) was the second-last novel by Walter Scott. 
 
Set in Constantinople at the time of the First Crusade, Count Robert of Paris portrays the impact of Western medieval values and attitudes on the sophisticated Romano-Greek classical society of the Byzantine Empire. The two main characters are Count Robert, a Frankish knight, and Hereward, an Anglo-Saxon refugee from the Norman conquest of England, serving as a mercenary soldier in the Varangian Guard of the Emperor Alexios I Komnenos. Count Robert was an actual but minor historical figure who disrupted negotiations between the Crusader leaders and the Emperor by occupying the latter's throne when it was temporarily vacated.
