This portrait of Amédée Thierry in ceremonial dress, painted by Jean-Léon Gérôme in 1863, shows the author of the Histoire des Gaulois, published between 1828 and 1845. He became very well-known as the first writer to popularise the figure of Vercingetorix. He was appointed a member of the Commission de Topographie des Gaules in 1858.
