A new genre of lifestyle and etiquette literature sprang up, of which the greatest was The Book of Civilised Man, written by Daniel of Beccles. He instructs the aspiring gentleman on how to behave in an enormous variety of social situations: in church, as a page in a noble household, at the dinner table, as a guest, in the street (don't eat in the street and don't peer into other people's windows), in a brothel -- and many more. He tells you when, where and how you can urinate, defecate, spit, belch and fart politely. He offers advice on how to live a long, healthy and happy life, what to eat and drink, with some recipes thrown in, discusses exercise, when to take baths, how often to have sex. Moderation in all things is the guiding principle, seasonally adjusted: in summer, for example, you should cut back on hot baths and sex. Cheerful songs will keep you in a good mood. Cultivate entertaining conversation, avoid quarrels, and get yourself some new clothes now and again.
Or Richard of Devizes thoughts on London:
Whatever evil or malicious thing can be found anywhere in the world can also be found in that city. There are masses of pimps. Do not associate with them. Do not mingle with the crowds in the eating-houses. Avoid dice, gambling, the theatre and the tavern. You will meet more braggarts there than in the whole of France. The number of parasites is infinite. Actors, jesters, smooth-skinned lads, Moors, flatters, pretty boys, effeminates, pederasts, singing and dancing girls, quacks, belly-dancers, sorcerers, extortioners, night-wanderers, magicians, mimes, beggars, buffoons.Hmmm. Typing this, I realize that it's been way too long since I've been to London.
