Clifford Ando’s research focuses on the histories of religion, law and government in the ancient world. His first book centered on the history of political culture in the provinces of the Roman empire, and he continues to write and advise on topics related to the provincial administration, the relationship between imperial power and local cultural change, and the form and structure of ancient empires. He has also written extensively on ancient religion. Significant themes were the connection of religion to empire and imperial government, especially in relation to pluralism and tolerance; and problems of representation in the use of objects in ritual. His current projects include a study of Latin as a language of the law and a study of legal theory in contexts of weak state power.
He is also general editor of Roman Statutes: Renewing Roman Law, a collaborative project that will produce a new edition, translation and commentary on all epigraphically-preserved Roman laws. The project is supported by grants from the The Gladys Krieble Delmas Foundation, the Neubauer Collegium, and the National Endowment for the Humanities.
