Context: Nobody is familiar with his own profile, and it comes as a shock, when one sees it in a portrait, that one really looks like that to people standing beside one. For one's full face, because of the familiarity that mirrors give it, a certain toleration and even affection is felt; but I must say that when I first saw the model of the gold piece that the mint-masters were striking for me I grew angry and asked whether it was intended to be a caricature. My little head with its worried face perched on my long neck, and the Adam's apple standing out almost like a second chin, shocked me. But Messalina said: "No, my dear, that's really what you look like. In fact, it is rather flattering than otherwise."
