THE SCENE: Ok, you finally got an audience before the king. But you have a fashion problem: should you wear your cloak (mantle) or not? Fortunately, you don’t need to suffer in silence, since the 13th century Norwegian etiquette book The King’s Mirror settles this question authoritatively.
THE TEXT: If a man appears before magnates wrapped in his cloak, he shows in that way that he regards himself as an equal to them in whose presence he is; for he comes clad in all his finery like a lord, and acts as if he need not serve any one. But if he lays aside his cloak, he shows that he is ready for service, if the one who is entitled to receive rather than to do service is willing to accept it. Likewise there are instances of this other fact, which often necessitates caution, that many are envious of a king; and if his enemy is rash and bold, he can indeed come before the king with hidden perils and murderous weapons, if he is allowed to wear his mantle; but he cannot easily accomplish this if he comes without his cloak. It is therefore evident that he was a wise man who first ordained the formality that a man should appear without a mantle before great lords and especially before kings. For that custom has since led to greater security against secret treason which could easily be hidden under the cloak, if it were worn. The custom has also promoted fair dealing and concord among men, for in this matter they all enjoy the same rights; and this being the accepted custom, one is not suspected or searched more than others.
