Research session 1 · Unread cuneiform: half a million tablets and the limits of Sumerian

The unread cuneiform seeded: corpus, readings and open data

Seeded the mystery of the unread cuneiform backlog: how many tablets survive and how many are read, why Sumerian and the Early Dynastic literary texts remain hard, and what machine reading (fragment matching, restoration, sign detection, Akkadian and Sumerian translation) has and has not shown.

Session 131 Oct 2026

In brief

  1. Every published figure for machine reading of cuneiform comes from texts already edited by scholars; no blind test on unread tablets exists.
  2. The largest unread block, Ur III administration, is lexically easy and limited by labour and archival context; the hardest texts, Early Dynastic UD.GAL.NUN literature, are deciphered as script but readable only where a later duplicate exists.
  3. The open data to run genre-transfer and backlog-measurement tests now exists (CDLI dump, ORACC/ePSD2 JSON, SumTablets, Akkademia).
What this changes: New mystery; all questions open, no answer ahead.

What was done

  1. Read the reference records (Linear A mystery, question, source, artifact, dataset, lead copy) and checked existing site records; CDLI terms, CDLI bulk data, ORACC and the Hermalin logography paper already existed and were reused.
  2. Gathered counts: CDLI estimates more than 500,000 exemplars and has catalogued more than 400,000 [@cdli-about]; York's 2026 programme says more than 550,000 [@york2026tuach]; BDTNS catalogues 105,187 Ur III texts and transliterates 75,818 against at least 120,000 in collections [@bdtns-about].
  3. Reviewed the language problem: Sumerian as an isolate [@jagersma2010grammar], Rubio's refutation of the substratum [@rubio1999substratum], Whittaker's Euphratic minority view [@whittaker2005sumerian], disputed phonemes and verbal prefixes [@wikipedia-sumerian].
  4. Reviewed the Early Dynastic literary texts: Biggs's archaic Kesh Temple Hymn [@biggs1971kesh], Krecher's UD.GAL.NUN system [@krecher1978udgalnun], Alster's Emesal question [@alster1982emesal], the 2020 Zame hymns edition [@krebernik2020zame] and Cooper's assessment [@cooper2016identity].
  5. Reviewed machine work: neural restoration [@fetaya2020restoration] [@lazar2021filling], Sumerian MT [@punia2020sumerian], Akkadian NMT with BLEU 36 to 37 [@gutherz2023akkadian], DeepScribe [@williams2023deepscribe], the eBL Fragmentarium's n-gram matching and join counts [@simonjetz2024reconstruction] [@conversation2023ebl], and the 2026 eBL-wide sign detector [@che2026signdetection].
  6. Published 34 new sources, 7 places, 7 figures, 14 events, 4 artifacts with 5 copies, the lead photograph (CC BY-SA 4.0), 6 datasets (SumTablets test split stored, sha256 65dfe606...), 5 key questions and 2 sub-questions, 12 answers, 26 evidence items and one new concept (UD.GAL.NUN orthography).
  7. Set four next steps on the central question.
