[447] Charles the Great granted “ducatum Cenomannicum” to his son Charles in 790; Ann. Mettens. ad ann. (_Rer. Gall. Scriptt._, vol. v. pp. 346, 347). “Ducatus Cenomannicus, omnisque occiduæ Galliæ ora inter Ligerim et Sequanam constituta,” formed the share of Charles the Bald in 838; Ann. Bertin. ad ann. (_ib._ vol. vi. p. 199). [448] Ann. Bertin. a. 841 (_ib._ vol. vii. p. 60). [449] Chron. Fontanell. a. 850 (_ib._ p. 42). [450] The Chron. S. Maxent. (Marchegay, _Eglises_, p. 366), two Aquitanian chronicles (in Labbe, _Nova Bibl._, vol. i. pp. 291, 324) and Ademar of Chabanais (_Rer. Gall. Scriptt._, vol. vii. p. 226) date this 852; Regino and the Ann. Mettens. (_Rer. Gall. Scriptt._, vol. vii. p. 190) place it in 860. [451] Above, p. 102. Part at least of this ceded territory must have been soon regained; for it extended “usque ad viam quæ a Lotitiâ Parisiorum Cæsarodunum Turonum ducit.” Ann. Bertin. a. 856 (_Rer. Gall. Scriptt._, vol. vii. p. 71). [452] Frodoard. Chron. a. 924 (_Rer. Gall. Scriptt._, vol. viii. p. 181). See above, p. 124. [453] _Acta Pontif. Cenoman._, c. 29 (Mabillon, _Vet. Anal._, p. 303). [454] See the story of his struggles with Avesgaud in _Acta Pontif. Cenoman._, c. 30 (as above, pp. 303, 304). [455] Necrol. S. Pet. de Culturâ (Le Mans), quoted in _Rer. Gall. Scriptt._, vol. xi. p. 632. Ademar of Chabanais (_Rer. Gall. Scriptt._, vol. x. p. 161) seems to imply that he had contracted a mortal disease in his Angevin dungeon. [456] _Acta Pontif. Cenoman._, c. 31 (Mabillon, _Vet. Anal._, pp. 305, 306). From the dates there given, Avesgaud must have died in October 1035, about five months before Herbert Wake-dog. [457] _Acta Pontif. Cenoman._, as above (p. 305).
