R. Tzidkiyah ben Avraham (the Anav)

R. Tzidkiyah ben Avraham HaRofeh (c. 1210-1280) of Rome was a leading Italian Rishon and the author of Shibbolei HaLeket — the foundational compendium of Italian-Roman Jewish minhag and halacha. The work surveys Tannaitic and Amoraic sources together with the rulings of Geonim, Rashi, and the Tosafists, organizing them into a coherent practical guide for Italian Jewish life. Tzidkiyah was a member of the Anav family — one of the founding Roman Jewish dynasties dating back to the late Roman empire — and likely served as a community physician (hence HaRofeh).
