The antiquities of Bretagne, which have been the subject even of political controversy, are illustrated by Hadrian Valesius (Notitia Galliarum, sub voce Britannia Cismarina, p. 98-100), M. d'Anville (Notice de l'Ancienne Gaule,Corisopiti, Curiosolites, Osismii, Vorganium, p. 248, 258, 508, 720, and Etats de l'Europe, p. 76-80), Longuerue (Description de la France, tom. i. p. 84-94), and the Abbe de Vertot (Hist. Critique de l'Etablissement des Bretons dans les Gaules, 2 vols. in 12mo. Paris 1720). I may assume the merit of examining the original evidence which they have produced.
