AUTHORITIES.--The history of maps is dealt with ably in Vivien de Saint Martin's _Histoire de la géographie_ (Paris, 1875), and in Peschel's _Geschichte der Erdkunde_ (2nd ed. by Sophus Ruge, Berlin, 1877), as also by W. Wollkenhauer (_Leitfaden zur Geschichte der Kartographie_, Breslau, 1895), and H. Zondervan (_Allgemeine Kartenkunde_, Leipzig, 1901). J. Lelewel's _Geographie du moyen âge_, with an atlas (Brussels, 1850-1857), has in part been superseded by more recent researches. There are, however, a number of works, beautifully illustrated, which deal fully with particular periods of the subject. Among these may be mentioned Konrad Miller's _Die ältesten Weltkarten_ (Stuttgart, 1895-1897), which only deals with maps not influenced by the ideas of Ptolemy. The contents of the following collections are more varied in their nature, viz. E. F. Jomard's _Monuments de la géographie_ (Paris, 1862), Santarem's _Atlas composé de mappemondes et de portulans_, &c. (Paris, 1842-1853, 78 plates). A. E. Nordenskiöld's _Facsimile Atlas_ (Stockholm, 1889), Gabriel Marcell, _Choix de cartes et de mappemondes XIV^e et XV^e siècles_ (Paris, 1896). C. H. Coote's _Remarkable Maps of the XVth, XVIth and XVIIth Centuries reproduced in their Original Size_ (Amsterdam, 1894-1897), and _Bibliotheca lindesiana_ (London, 1898) with facsimiles of the Harleian and other Dieppese maps of the 16th century. Nautical charts are dealt with in A. E. Nordenskiöld's _Periplus_ (Stockholm, 1869), and Th. Fischer's _Sammlung mittelälterlicher Welt- und Seekarten_ (Vienna, 1886). The discovery and mapping of America are illustrated by F. Kunstmann's _Entdeckung Amerikas_ (Munich, 1859), K. Kretschmer's _Atlas zur Entdeckung Amerikas_ (Berlin, 1892), G. Marcel's _Reproductions de cartes et de globes relatives à la découverte de l'Amérique du XVI^e au XVIII^e siècle_ (Paris, 1893) and E. L. Stevenson's _Maps Illustrating the early Discovery and Exploration of America, 1502-1530_ (New Brunswick, N.J., 1906). In addition to these collections, numerous single maps have been published in geographical periodicals or separately. See also V. Hantzsch and L. Schmidt, _Kartog. Denkmäler zur Entdeckungsgeschichte von Amerika, Asien, Australien und Afrika aus der k. Bibliothek zu Dresden_ (Leipzig, 1903), and the Crown Collection of photographs of American maps (1600-1800), selected and edited by A. B. Hulbert (Cleveland, 1904-1909).
