Alchemy, astrology and medicine (before the triumph of germ theory): three worthless intellectual systems which provided a good living for many into the 18th century and even beyond. Alchemy turned into chemistry; astrology was divorced by astronomy; and medicine (which might have become Pasteurism or Listerism) somehow kept its old name while abandoning all its old therapies. There have always been people with the good sense to say that alchemists and astrologers were charlatans, and doctors were more likely to kill you than cure you, but few listened. After all, all three could claim to be ancient, respectable forms of learning. And all three were too good to be true.

In 1651, the poet Andrew Marvell was working for the parliamentarian military hero Sir Thomas Fairfax, tutoring his daughter Mary on Fairfax’s Nun Appleton estate near York. When he wasn’t delivering language lessons to his young charge, Marvell was busy composing one of the most astonishingly experimental poems of the 17th century. Opera in the 1650s first seeded the idea that women might be able to act and entertain for money in public ‘Upon Appleton House’, dedicated to Thomas Fairfax, is, on the one hand, just another variety of early modern patronage poem in which a writer praises a member of the aristocracy and their values in return for favour
