Numa Denis Fustel de Coulanges (French: [kulɑ̃ʒ]; 18 March 1830 – 12 September 1889) was a French historian. Joseph McCarthy argues that his first great book, The Antique City (1864) was based on his in-depth knowledge of the primary Greek and Latin texts. The book argued that:
Born in Paris, of Breton descent, after studying at the École Normale Supérieure he was sent to the French School at Athens in 1853, he directed some excavations in Chios, and wrote an historical account of the island.
After his return he filled various educational offices, and took his doctorate with two theses, Quid Vestae cultus in institutis veterum privatis publicisque valuerit and Polybe, ou la Grèce conquise par les Romains (1858). In these works his distinctive qualities were already revealed. His minute knowledge of the language of the Greek and Roman institutions, coupled with his low estimate of the conclusions of contemporary scholars, led him to go directly to the original texts, which he read without political or religious bias. When, however, he had succeeded in extracting from the sources a general idea that seemed to him clear and simple, he attached himself to it as if to the truth itself.
From 1860 to 1870 he was professor of history at the faculty of letters at Strasbourg, where he had a brilliant career as a teacher, but never yielded to the influence exercised by the German universities in the field of classical and Germanic antiquities.
It was at Strasbourg that he published his remarkable volume La Cité antique (1864), in which he showed forcibly the part played by religion in the political and social evolution of Greece and Rome. The book was so consistent throughout, so full of ingenious ideas, and written in so striking a style, that it ranks as one of the masterpieces of the French language in the 19th century. By this literary merit Fustel set little store, but he clung tenaciously to his theories. When he revised the book in 1875, his modifications were very slight, and it is conceivable that, had he recast it, as he often expressed the desire to do in the last years of his life, he would not have abandoned any part of his fundamental thesis.
