AINIDAE SIMON DOMINIQUE THIERRY (1797-1873) was the younger brother of Augustin, and was born on the 2d August 1797. He began life as a journalist (after an essay, like his brother, at schoolmastering), was connected with the famous romantic harbinger the Globe, and obtained a small Government clerkship. His first book was a brief history of Guienne in 1825, and three years later appeared the Histoire des Gaulois, which was received with much favour, and obtained him, from the royalist premier Martignac, a history professorship at Besanyon. He was, however, thought too liberal for the Government of Charles X., and his lectures were stopped, with the result of securing him, after the revolution, the important post of prefect of the Haute-SaSne, which he held eight years. During this time he published nothing. In 1838 he was transferred to the council of state as master of requests, which post he held through the revolution of 1848 and the coup d'etat till 1860, when he was made senator - a paid office, it must be remembered, and, in effect, a lucrative sinecure. He also passed through all the ranks of the Legion of Honour, became a member of the Academie des Inscriptions in 1841, and in 1862 received the honorary degree of D.C.L. at Oxford. He had, except during the time of his prefecture, never intermitted his -literary work, being a constant contributor to the Revue des Deux Illondes, his articles (usually worked up afterwards into books) almost all dealing with Roman Gaul and its period. The chief were the Histoire d' Attila (1856), frequently reprinted, the Ilistoire de is Caule sous l'Administration Romaine (1840-2), a Tableau de l'Empire Romain, and, in imitation of his brother, certain Reeits of Roman history, a book on St Jerome in 1867, and one on Chrysostom and Eudoxia in 1873. He died March 27, 1873.

His literary and historical genius was perhaps inferior to his brother's, and be exhibits more of the defects of the anecdotic method of writing history, but he shared Augustin's passion for going to the fountainhead and for animating the drybones of mere chronicles and mere academic discussions with accounts of the life of peoples.
