Archbishop Even of Dol, a learned man, declares on Easter day 1082 that the sea nomads originated in fact from Atlantis, the lost island beyond the columns of Hercules, in Plato's writing. After meeting Castilian and Portuguese traders, some sea-nomads starts ferrying pilgrims across the Bay of Biscay, from Brittany to Galicia and Santiago del Campo de las Estrellas (Compostella). There, they re-established contacts with the Zenet from Galicia. From now on, the compass was pointing toward a lost country in the Atlantic, maybe the legendary Atlantis, or the mythical Frysland, or even Thyle (Thule), or simply, the Paradise. In 1257, a sea nomad from the isle of Jersey, serving as pilot, follows a Castillan ship to Tunsberg in Norway. The ship's crew had for mission to forge an alliance with the Norse King against the Danes. On their way back, the nomad, who was an excellent navigator, drew charts, which he gave to various nomad's colonies and told them about the land of the Norse men. Since then a trading migration is established by nomads who spend the summer in the fjords of Norway and the winter in the "rias" of Galicia. Their trade was rivalling with the Hansa merchants. This made them unwanted in most harbours and trading centres of Northern Europe.
