Maimonides (Moses ben Maimon, acronym "Rambam," 1138–1204) was a Sephardic Jewish philosopher, physician, and legal codifier, born in Córdoba and active largely in Fustat (Cairo). His fourteen-volume *Mishneh Torah* set out to systematize the entire body of rabbinic law into a single, plainly organized code, and his *Guide for the Perplexed* is a landmark of medieval philosophy.

In this vault Maimonides anchors the oldest leg of the "suspicious perfection" cluster and its legal-epistemology corner: his codification at *Mishneh Torah*, Sanhedrin 9:1 holds that a Sanhedrin whose judges *unanimously* find a capital defendant liable at the outset must exonerate him — total agreement read as proof that no one argued the required defense. The rule states, roughly 1,700 years before anyone had a statistical vocabulary for it, the same instinct Fisher and Simonsohn later formalized: perfect agreement is a symptom of a missing independent check, not stronger evidence.
