In 1529 a pupil of Apianus, Gemma Frisius, annotated his master’s work, when it was published at Antwerp, while an abridgment, _Cosmographiæ introductio_, was printed the same year (1529) at Ingoldstadt (Sabin, no. 1,739; Court, no. 21; _Bibl. Amer. Vet._, nos. 148, 149, and _Additions_, no. 88. There is a copy of the abridgment in Harvard College Library). The third edition of _Mela, cum commentariis Vadiani_ appeared at Paris in 1530, but without maps (cf. Carter-Brown, i. 97; Muller, 1877, no. 2,063; _Bibl. Amer. Vet._, no. 157); and again in 1532. (Sunderland, no. 10,124; Harrassowitz, list 61, no. 60). * * * * * It is not necessary to follow, other than synoptically, the various subsequent editions of these three representative books, with brief indications of the changes that they assumed to comport with the now rapidly advancing knowledge of the New World. =1533.= Apianus, full or abridged, in Latin, at Venice, at Freiburg, at Antwerp, at Ingoldstadt, at Paris (Carter-Brown, i. 591; _Bibl. Amer. Vet._, nos. 179, 202, and _Additions_, no. 100; Sabin, nos. 1,742, 1,757. Some copies have 1532 in the colophon). Apianus printed this year at Ingoldstadt various tracts in Latin and German on the instruments used in observations for latitude and longitude (Stevens, _Bibliotheca geographica_, no. 173, etc). Vadianus, in his _Epitome trium terræ partium_, published at Tiguri, described America as a part of Asia (Weigel, 1877, no. 1,574). He dated his preface at St. Gall, “VII. Kallen. August, M. D. XXXIII.” =1534.= Apianus in Latin at Venice (_Bibl. Amer. Vet., Additions,_ no. 106). The _Epitome_ of Vadianus in folio, published at Tiguri, with a map, “Typus cosmographicus universalis, Tiguri, anno M. D. XXXIIII,” which resembles somewhat that of Finæus, representing the New World as an island approaching the shape of South America. The Carter-Brown copy has no map (cf. Huth, v. 1508; Leclerc, no. 586, 130 francs; Carter-Brown, i. 112; Weigel, 1877, no. 1,576; _Bibl. Amer. Vet._, no. 189). An edition in octavo, without date, is held to be of the same year. It is usually said to have no map; but Quaritch (no. 12,475) has advertised a copy for £4,—“the only copy he had ever seen containing the map.” The _Huth Catalogue_, v. 1508, shows a copy with twelve woodcut maps of two leaves each, and four single leaves of maps and globes. The part pertaining to America in this edition is pages 544-564, “Insulæ Oceani præcipuæ,” which is considered to belong to the Asiatic continent (cf. Stevens, 1870, no. 2,179; Muller, 1872, no. 1,551; 1877, no. 3,293; Weigel, 1877, no. 1,575). =1535.= Apianus, in Latin, at Venice (Sabin, no. 1,743; _Bibl. Amer. Vet._, no. 202). Vadianus, in Latin, at Antwerp. (_Bibl. Amer. Vet._, 209; Huth, v. 1508; Court, no. 360).
