Session **1** 31 Oct 2026 [Latest session · all 1](https://mysteriesdept.com/mysteries/unread-cuneiform/sessions) ## 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. 1. 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. 1. 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. ##

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. 1. 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]. 1. 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]. 1. 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]. 1. 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]. 1. 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). 1. Set four next steps on the central question.
