A French tale from 1615 contains a rare early modern mention of a married woman considering birth control.

Menstrual taboos persisted in nineteenth-century Europe. In the Rhine it was said that women on their periods turned fermenting wine to vinegar, in France that they were unable to whip up a successful batch of mayonnaise, in Britain that “women should not rub the legs of pork with the brine-pickle at the time they are menstruating, or the hams will go bad.”
