[2] See for an interesting example of his early work his world map printed at The Hague in the year 1595. This map, in two hemispheres, lays down the track of Drake’s circumnavigation, 1577-1580, and that of Cavendish, 1586-1588. An original of this may be found in the Grenville Library of the British Museum, a reproduction in the work referred to below, n. [42].

Map of the World by Jodocus Hondius, with the title, ‘Novissima ac exactissima totius orbis terrarum descriptio magna cura & industria ex optimis quibusque tabulis Geographicis et Hydrographicis nuperrimisque doctorum virorum observationibus duobus planisphaerijs delineata. Auct. I. Hondio.’ New York, 1907. Facsimile in eighteen large sheets with key map and text.
[6] There is much doubt as to the correct reading of the date.
[7] These globes were acquired by Mr. Huntington at the auction sale held in the rooms of the American Art Association, November 24, 1916. They were listed in the catalogue of “Art treasures and Antiquities from the famous Davanzati Palace, and the Villa Pia, Florence, Italy,” under No. 575 as “a pair of sixteenth century Italian globes.” No other printed reference than that contained in this catalogue has hitherto appeared. It is hardly probable that a finer pair of these early Holland globes can be found in any of the museums or private libraries of Europe.

Chap. titled “De novo modo inveniendi longitudinem”; Ptolemaeus. Geographia. Chap. 4. Ptolemy here refers to an eclipse of the moon, in the year 331 B.C., which was observed in Arbela the fifth hour, in Carthage the second hour. He therefore noted a difference in time of three hours between the two places, and he therefore concluded the difference in longitude to be 43 degrees. Since the actual difference in longitude is but 34 degrees his error was of considerable magnitude, which found expression in his maps, and in the maps of those who followed him, as the greatest of geographical teachers, well into the seventeenth century. The method of determining longitude by means of the observation of the eclipses of the moon remained practically the only method until the end of the fifteenth century. Attention may here be called to work of Cassini and of other astronomers of his period. See II, 141.
