In 1526 a commissioner was appointed to correct the Spanish charts. Fernando Colon was charged with the revision, and in 1527 a map was made called _Carta universal en que se contiene todo lo que del mundo se ha descubierto fasta agora_. This map has been preserved, and a fac-simile is given in _Kohl_, _Beiden ältesten Karten von Am._ It shows the whole eastern coast line from the strait of Magellan to Greenland, and the western coast from Panamá to the vicinity of Soconusco, and indicates that the information in possession of the Spanish government was remarkably accurate and complete. Yucatan is represented as an island, and the discoveries on the Pacific side of South America are not laid down; otherwise this map varies but little except in names from a map made by Diego Ribero, in 1529, of which I shall give a copy. _Kohl_, _Beiden ältesten Karten von Am._, pp. 1-24; _Humboldt_, _Exam. Crit._, tom. ii. p. 184, and Preface to _Ghillany_. [1528.] Bordone, _Libro di Benedetto Bordone Nel qual si ragiona de tutte l'Isole del mondo_, Vinegia, 1528, gives maps of the larger American islands, and also a map of the world, the American part of which I copy from the original. No part of the western coast is shown, although the New World is represented as distinct from Asia. Kohl, _Beiden ältesten Karten von Am._, p. 34, mentions another work printed at Venice the same year, which has a map resembling that of Schöner in 1520. Pánfilo de Narvaez sailed from Spain in 1527 with five ships and 600 men, to conquer the northern shores of the Gulf of Mexico, and after losing some of his ships by storm, and many of his men by desertion, in cruising about Española, Cuba, and other islands, he landed in the vicinity of Tampa Bay April 14, 1528, and nearly all the company perished in an attempt to follow the coast toward Vera Cruz. _Cabeça de Vaca's Relation_, New York, 1871, pp. 13-20; _Herrera_, _Hist. Gen._, dec. iv. lib. iv. cap. iv.-vii.; lib. v. cap. v. [Illustration: MAP BY BENEDETTO BORDONE, 1528.] [1529.] Major, _Prince Henry_, pp. 440-52, entertains the opinion that Australia was discovered probably before 1529, and certainly before 1542. In 1529 was made the before-mentioned Spanish official map by Diego Ribero, which may be supposed to show all that was known by European pilots at that time of New World geography. It contains some improvements and additions to Colon's map of 1527 with the same title, although criticised, perhaps justly, by Stevens as partisan in its distribution of the new regions among the European powers. I give a copy reduced from the full-sized fac-simile in _Kohl_, _Beiden ältesten Karten von Am_.
