So people used their developing pharmacological knowledge to produce drug-laden balms—or, yep, "witch's brews." And to distribute those salves with maximum effectiveness, these crafty hallucinators borrowed a technology from the home: a broom. Specifically, the handle of the broom. And then ... you get the idea.

According to an investigation into witchcraft from 1324:

In rifleing the closet of the ladie, they found a pipe of oyntment, wherewith she greased a staffe, upon which she ambled and galloped through thick and thin.

And here's Jordanes de Bergamo, writing in the 15th century:

The vulgar believe, and the witches confess, that on certain days or nights they anoint a staff and ride on it to the appointed place or anoint themselves under the arms and in other hairy places.

So that explains the brooms. And what about the flying?

Part of the connection may have to do with brooms' place in pagan rituals. As a tool, the broom is seen to balance both "masculine energies (the phallic handle) and female energies (the bristles)"—which explains why it was often used, symbolically, in marriage ceremonies. But the more likely connection has to do with the fact that users of "witch's brew" were, in a very practical sense, using their ointment-laden broomsticks to get high. They were using their brooms, basically, to "fly."

Indeed. Here's how Gustav Schenk described the effects of tropane alkaloid intoxication, in 1966:

My teeth were clenched, and a dizzied rage took possession of me … but I also know that I was permeated by a peculiar sense of well-being connected with the crazy sensation that my feet were growing lighter, expanding and breaking loose from my own body. Each part of my body seemed to be going off on its own, and I was seized with the fear that I was falling apart. At the same time I experienced an intoxicating sensation of flying …. I soared where my hallucinations—the clouds, the lowering sky, herds of beasts, falling leaves … billowing streamers of steam and rivers of molten metal—were swirling along.

So there you have it, rye to flying brooms. But "witches" in the cultural imagination, of course, don't necessarily need re-purposed cleaning supplies to be accused of sorcery. In 1976, Linnda Caporael presented work suggesting that the Massachusetts of the late 17th century had been the unknowing victim of an outbreak of rye ergot. Her work is the subject of continued debate, but has been substantiated by later scholars: The Massachusetts of 1692 likely did see an outbreak of the fungus that had contributed, in other contexts, to "witch's brew."

The epicenter of the outbreak? Salem.
