Lex Mahumet pseudoprophete (English: Law of Muhammad the pseudo-prophet/false prophet) is the translation of the Qur'an into Medieval Latin by Robert of Ketton (c. 1110 – 1160 AD). It is the earliest translation of the Qur'an into a Western European language.[1]
In 1142 French abbot Peter the Venerable persuaded Robert to join a team he was creating to translate Arabic works into Latin in hopes of aiding the religious conversion of Muslims to Christianity. The translation of the Qur'an was the principal work of this collection, the Corpus Cluniacense. The undertaking was huge, taking over a year and filling over 100 folios (180 pages in modern print). This translation of the Qur'an became popular, with over 25 manuscripts still existing, together with two 16th-century prints. It was the standard translation for Europeans from its release until the 18th century.
