Roman emperors have long provided a template for autocrats and a warning for politicians, according to acclaimed historian Mary Beard. But not all emperors were cruel, bloodthirsty and decadent. Beard’s new book “Emperor of Rome” looks at the daily practicalities of their lives, as they managed budgets and troop deployments, headed public banquets and responded to petitions from their subjects. It also examines the ordinary Romans who made the imperial system function, including soldiers, aristocrats and the enslaved. We talk to Beard about what life was like in the corridors of power of ancient Rome and take your questions.
