This collection - an order by the Ministry of Education - was the first publication to bring together all the knowledge that had been accumulated about Celtic coins. In the preface, the author states: “In 1876, the Commission de Topographie des Gaules decided to publish a general catalogue of Gallic coins. It formed a subcommission, with de Saulcy, Charles Robert and Anatole de Barthélemy, joined later by Chabouillet and Muret.” The Commission de géographie historique de l'ancienne France took over the project, which in 1883 remained unfinished. On the suggestion of Xavier Charmes, Henri de La Tour was tasked with completing the atlas. The book contains descriptions of more than 2,000 Celtic coins. Today it remains an important reference work.
