The Dialogus de Scaccario, or Dialogue concerning the Exchequer, is a mediaeval treatise on the practice of the English Exchequer written in the late 12th century by Richard FitzNeal. The treatise, written in Latin,[1] and known from four manuscripts from the 13th century[2] is set up as a series of questions and answers, covering the jurisdiction, constitution and practice of the Exchequer. One academic said that "The value of this essay for early English history cannot be over-estimated; in every direction it throws light upon the existing state of affairs."[3] It has been repeatedly republished and translated, most recently in 2007.
