Jean Seznec (19 March 1905, in Morlaix – 22 November 1983, in Oxford) was a historian and mythographer whose most influential book, for English-speaking readers, has been La Survivance des dieux antiques, 1940, translated as The Survival of the Pagan Gods: Mythological Tradition in Renaissance Humanism and Art, 1953. Expanding the scope of work by Warburg Institute scholars Fritz Saxl and Erwin Panofsky, Seznec presented a broad view of the transmission of classical representation in Western Art.
Seznec won a place at the French Academy in Rome in 1929, where he studied under Émile Mâle, whose methodology influenced his own work. At the outbreak of World War II, Seznec returned from his position in Florence as director of the French Institute, to enlist. His major work was published in 1940, just as France fell. After the war he accepted a position in Romance Languages and Literatures at Harvard University, where he taught from 1941 to 1949. He then was elected Marshal Foch Professor of French Literature at Oxford University, a chair that he held, along with a fellowship of All Souls College, Oxford, from 1950 until his retirement in 1972. He edited exhibition catalogues and the edition of Paris Salon art criticism written by the Encyclopédiste Denis Diderot between 1759–81, an important primary resource for understanding the history of taste. A conference was held in his memory at the Warburg Institute in 2000.
