At about this time war and fighting sprang up between the nation of the Varni and soldiers who live on the island called Brittia; and it came about from the following cause. The Varni dwell beyond the Ister River, and extend as far as the northern ocean along the river Rhine, which separates them from the Franks and the other nations who dwell in that region. Now among all these nations which in ancient times dwelt on both sides of the Rhine river each people had its own particular name, but the whole group was called in common Germans. The island of Brittia lies in this part of the ocean not far from the coast, being about two hundred stades off and approximately opposite the mouth of the Rhine, and between the islands of Britain and Thule. For while Britain lies to the west about in line with the extreme end of Spain, separated from the continent by a distance which at the least is about four hundred stades, Brittia is towards the rear of Gaul, that side namely which faces the ocean, being, that is, to the north of both Spain and Britain. And Thule, as far as men know at any rate, is situated towards the extremity of the northern ocean. But the description of Britain and of Thule has been set down by me in the preceding narrative. The island of Brittia is inhabited by three very numerous nations, each having one king over it. And the names of these nations are Augili, Frissones, and Brittones, the last being named from the island itself. And so great appears to be the population of these nations that every year they emigrate thence in large companies with their women and children and go to the land of the Franks. And the Franks allow them to settle in the part of their land which appears to be more deserted, and by this means they say they are winning over the island. Thus it actually happened that not long ago the king of the Franks, in sending some of his intimates on an embassy to the Emperor Justinian in Byzantium, sent with them some of the Angili, thus seeking to establish his claim that this island was ruled by him. Such then are the facts relating to the island that is called Brittia.
