 The English "Assize of Bread and Ale" of 1266 listed extensive tables where the size, weight, and price of a loaf of bread were regulated in relation to grain prices.The baker's profit margin stipulated in the tables was later increased through successful lobbying from the London Baker's Company by adding the cost of everything from firewood and salt to the baker's wife, house, and dog.Since bread was such a central part of the medieval diet, swindling by those who were trusted with supplying the precious commodity to the community was considered a serious offense.
