Jean-Antoine Letronne
Jean Antoine Letronne (25 January 1787 – 14 December 1848) was a French archaeologist. Life. Born in Paris, his father, a poor engraver, sent him to study art under the painter David, but his own tastes were literary, and he became a student in the Collège de France, where it is said he used to exercise his already strongly developed critical faculty by correcting old translations of Greek authors and afterwards comparing the results with the latest and most approved editions. From 1810 to 1812 he travelled in France, Switzerland and Italy, and on his return to Paris  published a paper entitled "Essai critique sur la topographie de Syracuse", designed to elucidate Thucydides. Two years later appeared his "Recherches geographiques et critiques on the De Mensura Orbis Terrae of Dicuil". In 1815 he was commissioned by government to complete the translation of Strabo which had been begun by François-Jean-Gabriel de La Porte du Theil, and in March 1816 he was one of those who were admitted to the Academy of Inscriptions by royal ordinance, having previously contributed "On the Metrical System of the Egyptians". Further promotion came rapidly: in 1817 he was appointed director of the  École Nationale des Chartes, in 1829 inspector-general of the university, and in 1831 professor of history in the Collège de France. This chair he exchanged in 1838 for that of archaeology, and in 1840 he succeeded Pierre Claude François Daunou as keeper of the national archives. Meanwhile, he published, among other works, "Considérations générales sur l'évaluation des monnaies grecques et romaines, et sur la valeur de l'or et de l'argent avant la découverte de l'Amérique" in 1817, "Recherches pour servir à l'histoire de l'Egypte pendant la domination des Grecs et des Romains" in 1823, and "Sur l'origine grecque des  zodiaques pretendus egyptiens" in 1837. By the last-named he finally exploded a fallacy which had up to that time vitiated the chronology of contemporary Egyptologists. His "Diplômes et chartes de l'époque mérovingienne, sur papyrus et sur vélin" were published in 1844. The most important work of Letronne is the "Recueil des inscriptions grecques et latines de l'Égypte", of which the first volume appeared in 1842, and the second in 1848. Letronne is also known as one of the earliest proponents of the Flat Earth Myth.
