Antoinc Jean Letronne, a French archaeologist, born in Paris, Jan. 25, 1787, died there, Dec. 14, 1848. From the age of 14 he supported his mother and aided his brother to complete his studies as a painter; and while yet a youth became well known among the learned by his numerous restitutions of disputed passages in classic writers. In 1810-'12 he travelled in France, Italy, and Switzerland, and after his return his edition of the work of Dicuil on the measurement of the earth, and an article on the Pausanias of Clavier, caused him to be chosen by government to complete the translation of Strabo, begun by Laporte-Dutheil. He was appointed inspector general of the university in 1819, and professor of history in the college de France in 1831. In 1832 he became keeper of antiquities in the royal library. In 1838 he was appointed administrator of the college de France and professor of archaeology', and in 1840 succeeded Daunou as keeper of the archives of the kingdom. He distinguished himself by his refutation of the assertions of Dupuis and others relative to the "zodiacs" discovered at Esne and Denderah, in which he showed that, instead of belonging to an inconceivably remote antiquity, they were no older than the days of the Caesars. His great work, the Recueil des inscriptions grecqucs et latines de l'Egypte (2 vols. 4to, Paris, 1842, 1848), was unfinished at the time of his death.
