Orchésographie is full of gems. My favourite:

"naturally the male and female seek one another and nothing does more to stimulate a man to acts of courtesy, honour, and generosity than love. And if you desire to marry you must realise that a mistress is won by the good temper and grace displayed while dancing … And there is more to it than this, for dancing is practised to reveal whether lovers are in good health and sound of limb, after which they are permitted to kiss their mistresses in order that they may touch and savour one another, thus to ascertain if they are shapely or emit an unpleasant odour as of bad meat. Therefore from this standpoint, quite apart from the many other advantages to be derived from dancing, it becomes an essential in a well-ordered society.”

More on that book in the article here.

As for QE1, I reiterate that she did not dance La Volta in public, all the evidence is against it, not due to dizziness but for decorum and good politics, for reasons explained here.
