In tracing down the notices in print of John or Sebastian Cabot, we come now to a book of considerable interest, published in Venice in 1588, some years after the death of its author, Livio Sanuto. It was entitled _Geographica Distincta_, etc., and related in part to matters connected with naval science. The author was deeply interested in the subject of the variation of the needle, and having heard that Sebastian Cabot had publicly explained this subject to the King of England (supposed to be Edward VI., on Cabot’s return to England), he applied to the Venetian ambassador there resident to ascertain from Cabot himself where he had fixed the point of no variation. The information was accordingly procured and published by Sanuto. In the course of his investigations the author made use of a map composed by Cabot himself, in which the position of this meridian was seen to be one hundred and ten miles to the west of the island of Flores, one of the Azores. Mr. Biddle,[79] who dwells at some length on this volume, calls attention to the fact “that the First Meridian on the maps of Mercator, running through the most western point of the Azores, was adopted with reference to the supposed coincidence in that quarter of the true and magnetic poles.” Sanuto makes frequent reference to the map of Cabot in his book, and also makes mention of Cabot’s observations relating to the variation of the compass at the equator. I have already called attention to one of the legends on Cabot’s map of 1544, no. 17, which relates in part to the variation of the needle. In _Prima Parte_, lib. ii. fol. 17, Sanuto gives a brief account of Cabot’s voyage, which Mr. Biddle[80] says corresponds minutely with that which Sir Humphrey Gilbert derived from the map hung up in Queen Elizabeth’s gallery. Sanuto, however, evidently copied from Cabot’s letter in the preface of the third volume of Ramusio, from which also the language in Gilbert is drawn. In 1589 Hakluyt published his first folio of 825 pages entitled, _The Principal Navigations, Voyages, and Discoveries of the English Nation_, a monument of his industry as a collector. In this first folio Hakluyt included several pieces from his little quarto tract of 1582, and he collected and put into English other most important evidence relating to the discovery of North America by the Cabots. He gave the passage in Peter Martyr, the conversation in Ramusio, the extract from Gomara, added to those documents reprinted from the quarto tract, all of which have been here noticed in the order in which they appeared in print. It may be added that in the passage from Fabian Hakluyt introduced the name of John Cabot as the Venetian, though he allowed the name of Sebastian to stand in the heading, probably through inadvertence. He also brought the marginal date into the text. [Illustration: A SKETCH OF THE HAKLUYT-MARTYR (1587) MAP.
