In each Roman military camp, latrines were built, fed with running water from nearby streams. The analysis of the contents of the septic tank rinsed from these sanitary facilities allowed archaeologists to reconstruct the diet of Roman soldiers (it turns out that not only digging in the ground but also in… excrement can be extremely beneficial for science). The thing is, there are some remnants of the digested seeds there. Here in cold Britain, on the line of fortifications known as Hadrian’s Wall, products such as olives, figs and dates were often eaten, although apples were also not scorned.
