terrestrial globes, though no such globe of his is now known, and from his letters to Reuchlin we learn that he made no less than three celestial globes.119 One of the latter he sent to his friend, Probst Peter Wolf of Denkendorf, which represented the movements of the sun and of the moon. A second was constructed for Bishop von Dalberg of Worms, on which the stars were represented in gold.120 Nothing further is definitely known of these two globes. A third was constructed for Bishop Daniel of Constance, which is the one now to be found in that city’s library.121 This sphere has a diameter of 48 cm., rests upon a wooden base, and is furnished with a meridian and with a horizon circle. The forty-eight constellations of Ptolemy are represented on a dark background and are outlined in accord with recognized traditions. To a few of the constellations double names are given, as “Hercules” and “Genuflexus,” “Auriga” and “Agitator”. Stars of the first magnitude are especially distinguished by name, the majority of which are of Arabic origin, and more than one thousand stars are clearly indicated.

      The Canary Islands, and perhaps others in the eastern Atlantic, were known to the Romans, but appear to have been lost to the knowledge of the Europeans during the greater part of the middle ages, to be rediscovered in the period in which modern geographical exploration was being entered upon.

      From the above-named list of works, to which numerous additions might be made, a general notion of the beginnings of modern cartography can be obtained.

      Of the above-named works, that by Ravenstein is the most satisfactory, being a most scholarly and scientific treatment of his subject. His work is indeed a monument in the field of historical geography. Of the reproductions of the globe map, none surpasses the excellent facsimile in the form of globe gores which he prepared to accompany his studies. With the utmost care he deciphered the numerous legends and place names, admitting, here and there, the possibility of inaccuracy in the readings due to the damaged condition of the globe. Vignaud, H., in his Toscanelli and Columbus, pp. 182–186, gives a list of the numerous reproductions of the globe map, with a brief word concerning each. It may here be added that an excellent reproduction of the globe, mounted as is the original, and made for Dr. W. B. James of New York, in Nürnberg, the Ravenstein gores being pasted over the prepared ball, may be seen in the map department of The American Geographical Society. A similar reproduction of the globe, with mounting of wood instead of iron, was obtained by the author for exhibition in the Santa Maria, Spain’s Official Replica of the Flagship of Admiral Columbus, which was to have been exhibited in San Francisco in 1915. It failed, however, to reach its destination, and was returned to Chicago.
