Overview

The Aleppo Codex is a major manuscript witness to the Tiberian Hebrew biblical text and its Masoretic traditions of spelling, vocalization, cantillation, and annotation. Produced in the tenth century, it was later consulted by Maimonides and eventually safeguarded by the Jewish community of Aleppo. Parts of the manuscript disappeared amid violence surrounding the community in 1947, leaving scholars to reconstruct missing sections through testimony and related manuscripts. The Codex joins scribal precision, communal guardianship, loss, and modern textual scholarship. It remains foundational for critical editions of the Hebrew Bible.
