A tenant owes three days of week-work in a six-day week, plus rent in kind, plus compulsory paid use of the mill and oven. Why do historians treat the mill and oven charges as more burdensome than their small size suggests?

B. They fall on everything the household processes and eats, so they cannot be avoided or reduced

Rent is periodic and negotiable; a monopoly on grinding and baking is a levy on every meal, and it cannot be escaped by producing less for market. That is why banalités show up so consistently in the grievances of fourteenth- and fifteenth-century revolts, and why rebels made a point of destroying mills.
