This volume gathers the texts of the six lectures given by Arnaldo Momigliano at the University of California, Berkeley in 1961/62, which the author continued to revise and enrich over the years, yet never proceeded to publish.

This posthumous edition represents the final stage of processing the texts, which are part of a plan to explore the relationships between ancient historiography and contemporary developments in the field.
