Though it fails to appear on medieval lists of set-books, Cael. belongs to the group of ten speeches that arrived in France in the late eighth or early ninth century, perhaps from an insular center on the Continent, since they show errors typical of transcriptions from insular sources. One copy found its way to Tours, where it was transcribed (Paris. lat. 7794 = P, first half of the ninth century), another to Liège yielding various copies, of which the oldest are G (Brussels 5345, beginning of eleventh century) and E (Berlin lat. fol. 2o 252, beginning of the twelfth century). Another manuscript (Harley 4927 = H, copied in central France in the middle of the twelfth century) is used by editors beside PGE in the reconstruction of the ω hyparchetype, though it has been suspected of deriving directly from P. In addition, there is a second branch of the tradition (Ω) derived from the famous “uetus Cluniacensis” (Cluny 496 = C), a codex copied perhaps in the eighth century that was discovered in 1413 by Jean de Montreuil and made its way to Italy, where it was copied twice, in 1416–17 at Florence and ca. 1428, perhaps by Poggio, and then lost; it is reconstructed from the marginalia of Paris lat. 14749 (French) and from some Italian MSS. Recent editors have tended to proceed eclectically without preference for a particular MS or group of MSS.
