Not only ordinary English tourists, but English historical scholars have been led astray in the topography of early Angers by an obstinate local tradition which long persisted in asserting that the counts and the bishops of Angers had at some time or other made an exchange of dwellings; that the old ruined hall within the castle enclosure was a piece of Roman work, and had served, before this exchange, as the synodal hall of the bishops. The date adopted for this exchange, when I visited Angers in 1877 (I have no knowledge of the place since that time) was “the ninth century”; some years before it was the twelfth or thirteenth century, and the synodal hall of the present bishop’s palace, with its undercroft, was shown and accepted as the home of all the Angevin counts down to Geoffrey Plantagenet at least. The whole history of the two palaces--that of the counts and that of the bishops--has, however, been cleared up by two local archæologists, M. de Beauregard (“Le Palais épiscopal et l’Eglise cathédrale d’Angers,” in _Revue de l’Anjou et de Maine-et-Loire_, 1855, vol. i. pp. 246–256), and M. d’Espinay, president of the Archæological Commission of Maine-et-Loire (“Le Palais des Comtes d’Anjou,” _Revue historique de l’Anjou_, 1872, vol. viii. pp. 153–170; “L’Evêché d’Angers,” _ib._ pp. 185–201). The foundation and result of their arguments may be briefly summed up. The first bit of evidence on the subject is a charter (printed by M. de Beauregard, _Revue de l’Anjou et de Maine-et-Loire_, as above, vol. i. pp. 248, 249; also in _Gallia Christiana_, vol. xiv. instr. cols. 145, 146) of Charles the Bald, dated July 2, 851, and ratifying an exchange of lands between “Dodo venerabilis Andegavorum Episcopus et Odo illustris comes.” The exchange is thus described:--“Dedit itaque præfatus Dodo episcopus antedicto Odoni comiti, ex rebus matris ecclesiæ S. Mauricii, æquis mensuris funibusque determinatam paginam terræ juxta murum civitatis Andegavensis, in quâ opportunitas jam dicti comitis mansuræ sedis suorumque successorum esse cognoscitur. Et, e contra, in compensatione hujus rei, dedit idem Odo comes ex comitatu suo terram S. Mauricio æquis mensuris similiter funibus determinatam prænominato Dodoni episcopo successoribusque suis habendam in quâ predecessorum suorum comitum sedes fuisse memoratur.” As M. de Beauregard points out, the traditionary version--whether placing the exchange in the ninth century or in the twelfth--is based on a misunderstanding of this charter. The charter says not a word of the bishop giving up his own actual abode to the count; it says he gave a plot of ground near the city wall, and suitable for the count to build himself a house upon. Moreover the words “sedes fuisse memoratur” seem to imply that what the count gave was not his own present dwelling either, but only that which had been occupied by his predecessors. There can be little doubt that the Merovingian counts dwelt on the site
