When one imagines how the Qur'an was received and read in Latin Christendom, one does not tend to envision a great bastion of fairness. Burman ably shows that the picture is more complicated. What he offers is an exhaustive (albeit at times equally exhausting) examination of four principal Latin translations of the Qur'an (i.e., those by Robert of Ketton, Mark of Toledo, Flavius Mithradates, and Iohannes Gabriel Terrolensis [sponsored by Egidio da Viterbo]), with additional looks at some later renderings and also the work of Juan de Segovia.
With careful attention, Burman shows that, for the purposes of translation, they consistently set aside their polemical purposes and engaged the Qur'an seriously - they wrangled over philological concerns, they sought help in medieval Muslim tafsir literature, and in some cases they (well, Robert, more prone to paraphrase) even chose to render Qur'anic Arabic into the loftiest Ciceronian Latin style they could manage. They did not always grasp the Qur'an's grammar (and some better than others - Flavius Mithradates was more prone to bungling), but did occasionally achieve interesting and insightful renderings. (For instance, in Q. 22:5, Mark of Toledo rendered mudghatin mukhallaqatin wa-ghayr mukhallaqatin as carne consolidata et non consolidata).
Burman goes beyond the textual features of the translations themselves. He looks at the marginalia in all the manuscripts, some of which appear to descend from notes by the translators (which are consistently polemical). He scrutinizes tables of contents and indices; he examines what other texts the translations are bound with, and explores the ramifications for why certain editions of the Qur'an came to be collector's pieces in medieval Europe, "a desirable and exotic object useful for impressing one's wealthy friends." Burman even notes that manuscripts of the Qur'an in Latin came to be written out in the same textbook format that was popular within Scholasticism for the Bible and other key works deserving of study.
All in all, it can be easy to get bogged down in the details here, but if this particularly narrow subject is one that catches your attention, well, there's no other book quite like this one.
