Stevens and others have contended that this represents Columbus’ Ganges; but Varnhagen makes it stand for the Gulf of Mexico and the Mississippi,—a supposition more nearly like Reisch’s interpretation, as will be seen by his distinct separation of the new lands from Asia. Reisch is, however, uncertain of their western limits, which are cut off by the scale, as shown in the map; while on the other side of the same scale Cipango is set down in close proximity to it. [Illustration: STOBNICZA, 1512. It is held that this map shows the earliest attempt to represent on a plane a sphere truncated at the poles. Wieser (_Magalhaês-Strasse_, p. 11) speaks of a manuscript copy of Stobnicza’s western hemisphere, made by Glareanus, which is bound with a copy of Waldseemüller’s _Cosmographiæ introductio_, preserved in the University Library at Munich. Cf. Vol. III. p. 14, with references there, and Winsor’s _Bibliography of Ptolemy_ sub anno 1512; Harrisse, _Notes on Columbus_, p. 178, and _Bibl. Amer. Vet._, nos. 69 and 95, and _Additions_, no. 47. The only copies of the Stobnicza _Introductio_ in this country lack the maps. One in the Carter-Brown Library has it in fac-simile, and the other was sold in the Murphy sale, no. 2,075.] [Illustration: SCHÖNER. Fac-simile of a cut in Reusner’s _Icones_ (Strasburg, 1590), p. 127. Cf. on Schöner’s geographical labors, Doppelmayr’s _Historische Nachricht von den nürnbergischen Mathematikern und Künstlern_ (1730); Will und Nopitsch’s _Nürnbergisches Gelehrten-Lexicon_ (1757); Ghillany’s _Erdglobus des Behaim und der des Schöner_; and Varnhagen’s _Schöner e Apianus_ (Vienna, 1872).] It has been supposed that it was a map of this type which Bartholomew Columbus, when he visited Rome in 1505, gave to a canon of St. John Lateran, together with one of the printed accounts of his brother’s voyage; and this canon gave the map to Alessandro Strozzi, “suo amico e compilatore della raccolta,” as is stated in a marginal note in a copy of the _Mundus novus_ in the Magliabecchian library.[432] Columbus is said to have had a vision before his fourth voyage, during which he saw and depicted on a map a strait between the regions north and south of the Antillian Sea. De Lorgues, with a convenient alternative for his saintly hero, says that the mistake was only in making the strait of water, when it should have been of land! [Illustration: SCHÖNER, 1515.
