MARQUARDT, JOACHIM (1812-1882), German historian and writer on Roman antiquities, was born at Danzig on the 19th of April 1812. He studied at Berlin and Leipzig, held various educational appointments from 1833 onwards at Berlin, Danzig and Posen, and became in 1859 head of the gymnasium in Gotha, where he died on the 30th of November 1882. The dedication of his treatise Historiae equitum romanorum libri quatuor (1841) to Lachmann led to his being recommended to the publisher of W. A. Becker's Handbuch der romischen Alterthumer to continue the work on the death of the author in 1846. It took twenty years to complete, and met with such success that a new edition was soon called for. Finding himself unequal to the task single-handed, Marquardt left the preparation of the first three volumes (Romisches Staatsrecht) to Theodor Mommsen, while he himself contributed vols. iv.-vi. (Romische Slaalsvcrwaltung, 1873-1878; 2nd ed., 1881-1885, vol. v. by H. Dessau and A. von Domaszewski, vol. vi. by G. Wissowa) and vol. vii.(DasPrivatleben der Romer, 1879-1882; 2nd ed., by A. Mau, 1886). Its clearness of style, systematic arrangement and abundant references to authorities ancient and modern, will always render it valuable to the student.
