The Invention of Islamic Invention

A single prolific Wikipedia editor known as Jagged_85 manufactured or exaggerated a large swath of claims crediting medieval Muslim scholars with inventions and discoveries they did not originate. Between 2005 and 2012 he made tens of thousands of edits (over 87,000) that inserted assertions - Muslims invented funnels and sieves; al‑Razi discovered sublimation; Jabir ibn Hayyan created “cheese glue”; Ibn Sahl first described the parabolic mirror; Avicenna coined momentum; al‑Jazari invented the crank and feedback control - often attaching real but misread or misapplied sources. Those edits looked scholarly but stretched citations beyond what sources supported, sometimes contradicting the cited texts. Some fabricated concepts, like “Avicennian logic,” were propagated into academic discourse despite lacking foundation in the referenced literature.

The mechanism of spread was simple and pernicious: scholars, journalists, museum curators and educators leaned on Wikipedia summaries and bibliographies rather than primary sources, enabling jagged_85’s fabrications to launder into books, papers, exhibits and news stories. Specific examples include a Science Museum exhibit and a CNN writeup repeating a false claim about al‑Jazari’s crank, and public figures like Sean Carroll quoting misattributed claims about Avicenna. The episode demonstrates how plausible, citation‑laden falsehoods can become entrenched in the shared information environment when verification falters, producing persistent historical myths that survive correction.
