I've already posted about the stiff, intricate and often absurd rules of etiquette that regulated life at Versailles and against which Marie Antoinette often rebelled. Here are a couple more examples:
The Queen could drink nothing by night or by day but from the hand of the highest in rank of the women present, nor could this last accept the glass and the water save from the hand of a page. The King must not eat at all until he had performed an ablution like a priest: the vessels of this and the napkin were sacred; rather than put them to a profane use, when they had once done their service they were destroyed by fire.
Marie Antoinette by Hilaire Belloc
