partial / older only. An English translation exists but is partial or older than the critical edition. The gap is a modern, complete translation from the original. A rendering of a daughter version does not count here: it is recorded on the dossier of the text it actually translates.
Why this is in the register
HOLLIS author search 'Pachymeres' (71 hits) and 'Pachymeres English translation history Byzantium' show the standard edition is Failler's CFHB 24 (1984; reprint 1999-2000), Greek with facing French, plus Failler's French 'version breve' (2001-2004) and English translations only of his philosophical commentaries. The sole English rendering of the history is Nathan J. Cassidy's PhD thesis (University of Western Australia, 2004), which covers Books 1-2 only; a copy is on archive.org. No English translation of Books 3-13 was found.
13 books, the fullest Greek narrative of 1261-1308 (Michael VIII and Andronikos II): the loss of Anatolia, the Union of Lyons, the Arsenite schism. A classicizing history, not a chronicle. Only the first two books (1261-1266) exist in English, and only as an unpublished thesis.
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). Together the two volumes carry the whole 13-book history with Possinus' Latin version; both need column-crop re-OCR (tesseract -l grc) for the Greek. Duplicate scans with smaller page images: patrologiaecursu0143mign (810 pp) and patrologiaecursu0144mign (544 pp), page images 2299x3615 - their text layers are the same Latinised OCR. Failler's CFHB 24 edition (1984) is in copyright and not on IA.
