“LORD, DECLARE YOUR words through my mouth; feed me the crumbs from your table as your hound, baying for you against the rabid wolf.” This prayer was written in 854 in Umayyad Córdoba by Paulus Alvarus (ca. 800– 861), a Christian layman whose Indiculus luminosus (Enlightened Little List) survives as the earliest Latin treatise to deal extensively with the Prophet Muḥammad. While it enjoyed little success in subsequent generations, surviving in a single, damaged manuscript, scholars have studied the Indiculus as a glimpse into the so-called Córdoban martyrs’ movement of the 850s, or more abstractly as evidence of early medieval Muslim– Christian interaction. Between 850 and 857, forty-eight individuals “intentionally sought their executions in Córdoba,” with some travelling a great distance to do so, “by publicly insulting the prophet Muḥammad and denying the truth of Islam, or refusing to return to Islam after apostatizing.” Against this backdrop, Alvarus wrote a text that may have begun as a speech to the Christian elites of Córdoba, wherein he cast himself as a prophet to galvanize his Christian compatriots to assert their Christianity publicly and so oppose Islam and, by extension, the ruling regime. Through his Indiculus luminosus, Alvarus thus asserted his own prophetic authority in order to discredit that of Muḥammad, whom Alvarus imagined in this text as his opponent.
Modern scholarship has often interpreted the Indiculus as a defence of the recent martyrs, as a call to martyrdom or violent rebellion, or even as an early formulation of holy war ideology.4 Further, these scholars tend to focus their analysis of the Indiculus on Alvarus's depiction of Muḥammad's sexuality or Alvarus’ apocalypticism. None of these studies have, however, noted Alvarus’ own prophetic claims and his adaptation of a mode of authoritative discourse, increasingly common in the politics of the Latin West, based upon claims of divine inspiration or revelation. This omission stems in part from the fact that, although Alvarus undoubtedly crafted much of his Indiculus to attack Muḥammad, he never used the Prophet's name: a point I will address below. Instead, weaving his own prophetic authority into the Indiculus, Alvarus worked to convince his Christian contemporaries that God supported his ideal of Christian behaviour and sought to undermine Muslim arguments for Muḥammad's prophethood.
