Authenticity and Scholarship

The authenticity of the codex as an early-10th-century Tiberian Masoretic Bible is not in question; its script, layout and Masoretic apparatus place it securely, and it underlies modern critical editions of the Hebrew Bible such as the Hebrew University Bible. The scholarly controversy concerns the missing leaves. The community's long-standing account was that they had burned in the 1947 synagogue fire. When conservators examined the recovered leaves, however, they found discoloration consistent with fungus and damp rather than scorching, and the edges showed no uniform fire damage.

This led scholars and, later, journalists to argue that a large part of the codex survived the riot intact and was subsequently lost, removed or privately retained during or after its journey to Israel, a claim explored at length in Matti Friedman's investigative book The Aleppo Codex (2012). Members of the Aleppo community and others have disputed elements of that reconstruction. A handful of detached leaves and a fragment have surfaced since, showing that at least some material escaped destruction. The custodian institutions present the codex as a Masoretic treasure whose textual authority is secure, while acknowledging that the fate of the missing two-fifths is genuinely unresolved. Both the tradition's account and the physical evidence are set out here without adjudicating between them.
