De Machometo ('On Muḥammad')[1] is a brief anonymous Latin tract on the life of Muḥammad from a Christian point of view. It begins in the reign of Pope Boniface IV (608–615).[2] Its account is cobbled together from a variety of sources, including the fifth dialogue of Petrus Alphonsi's Dialogi in quibus impiae Judaeorum confutantur, the Corozan legend and possibly the Libellus in partibus transmarinis de Machometi fallaciis from Vincent of Beauvais's Speculum historiale.[3][4] The composite account is very similar to the account of Muḥammad found in the Golden Legend.[5]

^This is the short title used in Bolton 2009 and Wood 2022, p. 122. The full title in the Copenhagen manuscript is Tractatus quomodo Machometus decepit Saracenos secundum diuersas opiniones ('a treatise about how Muḥammad deceived the Saracens according to different opinions'), which appears at the beginning and in the explicit.
