Peter the Venerable depicted Muhammad as a fraud taught Jewish and heretical fables

Evidence

Peter describes Muhammad as a poor, vile, unlettered Arab who achieved wealth and power through bloodshed, thievery, and intrigue. Finally realizing that a feigned religious vocation would serve his ambitions, he claimed that he was a prophet and usurped the authority of king. Then, at the bidding of Satan, a heretical Nestorian monk named Sergius came and joined Muhammad: together, along with several Jews, they forged a new heretical doctrine. “Muhammad, schooled in this way by the finest teachers—Jews and heretics—composed his Koran. He wove together, in his barbarous fashion, nefarious scripture from the fables of the Jews and the ditties of the heretics.” — John V. Tolan, Saracens, 842

Categorization

• ADDENDUM: Supplies a concrete medieval origin for the modern trope of Islam as a derivative corruption stitched from Jewish and Christian error, relevant to the vault claims mapped via Anidjar/Aziz/Razack.
• QUESTION: Trace whether the specific ‘Sergius the Nestorian monk as Muhammad’s secret teacher’ motif survives into modern Islamophobic discourse.
