We have a suspicion of this strait in another map which has been held to have had some connection with the drafts of Columbus, and that is the Ruysch map, which appeared in the Roman Ptolemy of 1508,[433] the earliest published map, unless the St. Dié map takes precedence, to show any part of the new discoveries. [Illustration: THE TROSS GORES, 1514-1519. Twelve gores of a globe found in a copy of the _Cosmographiæ introductio_, published at Lugduni, 1514 (?), and engraved in a catalogue of Tross, the Paris bookseller, in 1881 (nos. xiv. 4,924). The book is now owned by Mr. C. H. Kalbfleisch, of New York. Harrisse (_Cabots_, p. 182) says the map was engraved in 1514, and ascribes it to Louis Boulenger. (Cf. Vol. III. p. 214, of the present _History_.) There are two copies of this edition of the _Cosmographiæ introductio_ in the British Museum; and D’Avezac (_Waltzemüller_, p. 123) says the date of it cannot be earlier than 1517. Harrisse says he erred in dating it 1510 in the _Bibl. Amer. Vet._, no. 63. Cf. Winsor’s _Bibliography of Ptolemy_ sub anno 1522.] It seems from its resemblance to the La Cosa chart to have been kept much nearer the Columbian draft than the geographer of St. Dié, with his Portuguese helps, was contented to leave it in his map. In La Cosa the vignette of St. Christopher had concealed the mystery of a westerly passage;[434] Ruysch assumes it, or at least gives no intimation of his belief in the inclosure of the Antillian Sea. Harrisse[435] has pointed out how an entirely different coast-nomenclature in the two maps points to different originals of the two map-makers. The text of this 1508 edition upon “Terra Nova” and “Santa Cruz” is by Marcus Beneventanus. There are reasons to believe that the map may have been issued separately, as well as in the book; and the copies of the map in the Barlow Collection and in Harvard College Library are perhaps of this separate issue.[436] [Illustration: MÜNSTER, 1532. The distinctive features both of the La Cosa and the Ruysch drafts, of the Cantino map and of the Waldseemüller or St. Dié map of 1513, were preserved, with more or less modifications in many of the early maps. The Stobnicza map—published in an _Introductio_ to Ptolemy at Cracow in 1512—is in effect the St. Dié map, with a western ocean in place of the edge of the plate as given in the 1513 Ptolemy, and is more like the draft of Reisch’s map published three years later. There are other drawings of this map in Stevens’s _Notes_; in Nordenskiöld’s _Bröderna Zenos_ (Stockholm, 1883); etc.]
