Snow begins his journey at Monte Testaccio a vivid indication of the importance of Hadrian’s family olive oil business in Baetica. The Emperor Trajan was appointed guardian to the orphaned Hadrian who achieved his reputation leading the Emperor’s wars of Imperial expansion. Snow visits Trajan's Markets where Hadrian asserted his authority to rule following the death of his guardian. Reversing the expansionist policies of his predecessor Hadrian defined the Empire’s northern borders with a wall along the Danube-Rhine frontier and Hadrian's Wall, visited by Snow, in Northern England. Snow also visits the wall that defined the southern borders and the nearby city of Sbeitla in Tunisia which shows the prosperity this brought to the region.
