Christian polemicists claimed Arabic science was stolen from Latin sources

Evidence

After glorifying Isidore’s piety and learning, Lucas explains that his successor, a shifty Greek named Teodistus, “a wolf in sheep’s clothing,” stole several manuscripts of Isidore’s as-yet-unknown works in medicine and other sciences, then “out of hatred of the Faith, excising the truth and inserting errors, had them translated from Latin into Arabic by a certain Arab named Avicenna,” who pretended the works were his own. … Faced with the impressive edifice of Arabic science, Lucas responds that the Arabs stole it all from the good Isidore. — John V. Tolan, Saracens, 940

• XREF: An early textual ancestor of the modern trope that Islamic/Arab civilization contributed nothing original but merely copied the West — grounds an existing vault claim about cultural-appropriation narratives.
• SEED: Essay angle: the medieval invention of Avicenna as plagiarist of Isidore as the deep ancestor of modern claims that Islamic science merely transmitted Greek knowledge.
