Within the chorographic and taumasiographic production of the ancient world, C. Giulio Solino's Polyhistor has experienced in the last two decades an unexpected fortune after a more than century-long oblivion and now stands as the reference work for Latin geographical literature of late antiquity. The present volume collects the Proceedings of the international conference on this author and his cultural context held in Rome on February 16 and 17, 2022 under the auspices of the Italian Institute for Ancient History and is intended to be preparatory to the critical edition, translation and historical commentary of Solino, which a team of Italian scholars is preparing in accordance with a project promoted by the Institute itself.
