 Oresme is generally considered the greatest medieval economist. He presented his economic ideas in commentaries on the Ethics, Politics, and Economics, as well as an earlier treatise, De origine, natura, jure et mutationibus monetarum, the first comprehensive work upon money. In his De origine, natura, jure et mutationibus monetarum, of which he himself made a French translation under the title Traictié de la premiere invention des monnoies, Oresme argued that coinage belongs to the public, not to the prince, who has no right to vary arbitrarily the content or weight (Woodhouse 2017). By clearly delineating the destructive effects on a nation’s economy of a debasement of the currency, he influenced Charles V’s monetary and tax policies.
