At this time the seas of the north of Europe were infected by Scandinavian pirates. Sinclair, who had recognized in Zeno a clever mariner, attached him to himself, and with him conquered the country of Frisland, the haunt of pirates, who ravaged all the north of Scotland. In the maps at the end of the fifteenth and beginning of the sixteenth century this name is applied to the archipelago of the Faroe Islands, a reasonable indication, for Buache has recognized in the present names of the harbours and islands of this archipelago a considerable number of those given by Zeno; finally the facts which we owe to the Venetian navigator about the waters,--abounding in fish and dangerous from shallows,--which divide this archipelago, are still true at the present day. Satisfied with his position, Zeno wrote to his brother Antonio to come and join him. While Sinclair was conquering the Faroe Islands, the Norwegian pirates desolated the Shetland Islands, then called Eastland. Nicolo set sail to give them battle, but was himself obliged to fly before their fleet, much more numerous than his own, and to take refuge on a small island on the coast of Iceland. After wintering in this place Zeno must have landed the following year on the eastern coast of Greenland at 69 degrees north latitude, in a place "where was a monastery of the order of preaching friars, and a church dedicated to St. Thomas. The cells were warmed by a natural spring of hot water, which the monks used to prepare their food and to bake their bread. The monks had also gardens covered over in the winter season, and warmed by the same means, so that they were able to produce flowers, fruits, and herbs as well as if they had lived in a mild climate." There would seem to be some confirmation of these narratives in the fact that between the years 1828-1830 a captain of the Danish navy met with a population of 600 individuals at 69 degrees north latitude, of a purely European type. But these adventurous travels in countries of which the climate was so different from that of Venice, proved fatal to Zeno, who died a short time after his return to Frisland. An old sailor, who had returned with the Venetian, and who said he had been for many long years a prisoner in the countries of the extreme west, gave to Sinclair such precise and tempting details of the fertility and extent of these regions, that the latter resolved to attempt their conquest with Antonio Zeno who had rejoined his brother. But the inhabitants showed themselves everywhere so hostile, and opposed such resistance to the strangers landing, that Sinclair after a long and dangerous voyage was obliged to return to Frisland. These are all the details that have been left to us, and they make us deeply regret the loss of those that Antonio should have furnished in his letters to his father Carlo, on the subject of the countries which Forster and Malto-Brun have thought may be identified with Newfoundland.
