Tacitus, or rather his father-in-law Agricola, might remark the German or Spanish complexion of some British tribes. But it was their sober, deliberate opinion:
"In universum tamen aestimanti Gallos vicinum solum occupasse credibile est Eorum sacra deprehendas . . . sermo haud multum diversus" (in Vit. Agricol. c. xi.).
Caesar had observed their common religion (Comment. de Bello Gallico, vi. 13); and in his time the emigration from the Belgic Gaul was a recent, or at least an historical event (v. 12) . Camden, the British Strabo, has modestly ascertained our genuine antiquities (Britannia, vol. i. Introduction, p. ii.-xxxi.).
