How did they do it? Romans ate on ‘three couches’ (a triclinium) with a table separating them (see Wiki on triclinium). There is a garden re-creation of a triclinium at Fishbourne Roman Garden and one can find some photos on the web of students eating this way. When I first came across the idea, I assumed the couches were only for orgies, so that you could eat yourself sick and misbehave at will. But no, a triclinium seems to have been the normal way for wealthy people to eat. I tried arranging the sofa to eat in this way. It was not good for my digestion, drinking was difficult and I did not explore my earlier ideas. The only advantage I discovered was that if one was eating sloppy food without a knife or fork then it was easy to get one’s mouth vertically above the plate, as one still does for spaghetti. I remain puzzled, but here are some German students with a foodless triclinium and here is a painting of a Roman banquet.
