Why this is in the register

HOLLIS Primo 'Cyril of Alexandria "Thesaurus de sancta" trinitate' returns a single record, the 1638 Latin Opera: https://hollis.harvard.edu/discovery/search?query=any,contains,Cyril%20of%20Alexandria%20%22Thesaurus%20de%20sancta%22%20trinitate&tab=Everything&search_scope=MyInst_and_CI&vid=01HVD_INST:HVD2&offset=0 The variant 'Cyril of Alexandria "Thesaurus"' returns four records — a Greek lexicon (Thesaurus Graecae linguae), a 1514 Latin printing of the Thesaurus, and the 1638 Opera — with no English translation: https://hollis.harvard.edu/discovery/search?query=any,contains,Cyril%20of%20Alexandria%20%22Thesaurus%22&tab=Everything&search_scope=MyInst_and_CI&vid=01HVD_INST:HVD2&offset=0 'Cyril of Alexandria Trinity Thesaurus English' returns 0 records: https://hollis.harvard.edu/discovery/search?query=any,contains,Cyril%20of%20Alexandria%20Trinity%20Thesaurus%20English&tab=Everything&search_scope=MyInst_and_CI&vid=01HVD_INST:HVD2&offset=0 No Fathers of the Church, Ancient Christian Writers or Popular Patristics volume was located.

Cyril's principal anti-Arian dogmatic work, cast as a verse-by-verse refutation from Scripture rather than as exegesis proper; a 1514 Paris printing and the 1638 Opera are the pre-modern Latin witnesses recorded at Harvard. No English translation located, complete or partial.

Existing translations recorded

None recorded in English. Non-English versions, where they exist, are named in the evidence above.

Electronic text

No open electronic text was verified for this work. The Greek/Coptic/Geʿez may exist only in a print or subscription edition (Migne, CSCO, TLG, CMCL).

Scanned witnesses

Scan search: open scan — 2 candidate(s). PG 75 is one of the two volumes missing from the bulk IA item patrologia-volumes (file stems run 001-074, 076-165; no 075 and no 106), so no page-image scan of PG 75 was used. The 'patrologia' item's per-work PDF is the only Greek text found; it is a re-keyed digital text, not a scan. The 1638 Aubert Opera in 6 tomes exists on IA as Google items (e.g. bub_gb_MelhnLxO3dEC, PDM) but those are text-only (no PDF delivered), so they were not recorded as candidates. HathiTrust/Google page images were not reachable from this host.
