There are a large number of medieval Latin texts that mention or discuss the Prophet Muhammad. The one that is the focus of this text is called the “Vita Mahometi” (Life of Mahomet) and it was found in a manuscript in the locality of Uncastillo in the Aragon region of northern Spain. It has been argued that the work may have been written by a Jewish convert to Christianity (as in the same manuscript there is an anti-Judaism text written by a Jewish convert calling himself ‘Peter’). The work has been dated to the early 13th century CE.
