The Apocalypse of Elijah and the Gospel of Judas are among the most consequential non-canonical writings preserved in Coptic, the latest stage of the Egyptian language, written in a Greek-derived alphabet and attested in several dialects (notably Sahidic, Bohairic, Akhmimic, Lycopolitan, Fayyumic). The Apocalypse of Elijah, an Egyptian Christian apocalypse possibly drawing on earlier Jewish material, survives in Akhmimic (P. Heid. Kopt. 600), Sahidic (notably the Chester Beatty codex), and Greek fragments, mostly produced in the fourth to fifth centuries; it offers a rare window onto Egyptian eschatology, the Antichrist figure (the "Son of Lawlessness"), and martyrological discourse under Roman persecution. The Gospel of Judas, recovered in the Sahidic Codex Tchacos and published in 2006, has reshaped scholarship on early "Gnostic" Christianity. Both survive only in codicologically fragile witnesses—ideal yet demanding candidates for TEI encoding.

This poster presents two in-progress TEI P5 editions. Editorial interventions, such as lacunae, restorations, uncertain letters, nomina sacra, scribal corrections, are explicitly marked with <gap>, <supplied>, <unclear>, <damage>, <add>, and <subst>, each with @reason and @cert. Multiple witnesses are collated via <app>/<rdg> against a <listWit> apparatus. The header documents a custom POS taxonomy in <classDecl>, named entities in <listPerson>/<listPlace> linked to Pleiades and Trismegistos, and an explicit Coptic Scriptorium provenance for the linguistic layer.

Every token is wrapped in <w> with part-of-speech (@type: ACAUS, ACONJ, ADV, N, NPROP, V…), Coptic @lemma, and @xml:lang="Greek" on loanwords, generated by the Coptic Scriptorium NLP pipeline and harmonized with our parallel editions of the Gospel of Judas and Pistis Sophia. The Apocalypse of Elijah base text required ~2,000 systematic OCR corrections (ⲛ̄/ⲙ̄ normalization, spurious supralinear strokes stripped, ⲍ↔ϩ and ⲭ↔ϫ confusions resolved against Wintermute's English translation), all transparently recorded in <editorialDecl>.

The poster invites discussion on TEI customizations for under-resourced ancient languages and the philological auditability of OCR-derived editions.
