Gustav Seyffarth, a German archaeologist, born at Uebigau, Saxony, July 13, 1796. He studied at Leipsic, where in 1825 he became extraordinary professor of archaeology. In 1824 he published De Sonis Litterarum Groe-carum (Leipsic). He edited and continued Spohn's De Lingua et Litteris Veterum AEgyp-tiorum, (2 vols., 1825-'31), and published Ru-dimenta Hieroglyphices (1826). His Grund-sätze der Mythologie (1843) and Untersuch-ungen über das Geburtsjahr Christi (1846) involved him in bitter controversies. His peculiar theory of hieroglyphics he maintained against Champollion, and he now (1875) claims that the Champollionists have passed off his system as their own. In 1855 he emigrated to the United States, and was for six years professor in the Lutheran seminary of St. Louis. In 1857 he published at New York a "Summary of recent Discoveries in Biblieal Chronology, Universal History, and Egyptian Archaeology," both in English and German, and in 1860 a pamphlet in German refuting the chiliasts. He has for some time been engaged on a work entitled "The actual Historical Chronology of the Romans, Greeks, Babylonians," etc.

His last publication is "Clavis AEgyptiaca, a Collection of all Bilingual and some other Hieroglyphic Inscriptions, translated and explained".
