Recently, though, historians have begun to question the veracity of these tales of mass slaughter and martyrdom. Francesco Tateo argues that the earliest contemporary sources do not support the story of the eight hundred martyrs; such tales of religious persecution and conscious self-sacrifice for the Christian faith appeared only two or more decades following the siege. The earliest and most reliable sources describe the execution of eight hundred to one thousand soldiers or citizens and the local bishop, but none mention a conversion as a condition of clemency. Even more telling, neither a contemporary Turkish chronicle nor Italian diplomatic reports mention martyrdom. One would imagine that if such a report were circulating, humanists and preachers would have seized on it. It seems likely that more inhabitants of Otranto were taken out of Italy and sold into slavery than were slaughtered.
