"Representations of Saracens as "the other" abound in ... the earliest manuscripts of the 13th century to the copies of the early 15th century books. These images reinforce stereotypes of Muslims that depict them as barbarians, berserkers, idol worshipping pagans, and nothing less than the enemies of God and mankind. Highly racial and pejorative depictions of these figures highlight their negative qualities through dark skin and distorted facial features.
Despite this there are also many images from the manuscripts examined in this study that depict Saracens and Christians similarly and acknowledge certain admirable Saracens. The depictions of Saladin and Ferragut as western figures, kings and Knights no less, establish a different kind of representation of Saracen than the biased views of other depictions. Although individuals like Saladin and Ferragut are rare, this demonstrates that the artists of these manuscripts understood that these figures could be received favorably by their audiences. ...
By depicting them with western characteristics these figures were elevated from the standard Saracen topos and honored by the extension of a kind of pseudo western status to them. This is hardly an example of tolerance, for the favorable depiction of them is entirely on standard Christian terms, but it still displays a kind of nuanced understanding of the figures that is important to note. It demonstrates that Christians from the time understood Saracens as more than the monsters that they so often depict them with in the other manuscripts examined in this study..."
