““Roman history also demands a particular sort of imagination. In some ways, to explore ancient Rome from the twenty-first century is rather like walking on a tightrope, a very careful balancing act. If you look down on one side, everything seems reassuringly familiar: there are conversations going on that we almost join, about the nature of freedom or problems of sex; there are buildings and monuments we recognise and family life lived out in ways we understand, with all their troublesome adolescents; and there are jokes that we ‘get’. On the other side, it seems completely alien territory. That means not just the slavery, the filth (there was hardly any such thing as refuse collection in ancient Rome), the human slaughter in the arena and the death from illnesses whose cure we now take for granted; but also the newborn babies thrown away on rubbish heaps, the child brides and the flamboyant eunuch priests.””
