The Dialogue on Translation between a Lord and a Clerk, or Dialogus inter dominum et clericum, was written by John Trevisa. Along with the dedicatory Epistle, it forms the introduction to his 1387 translation of the Polychronicon of Ranulf Higden, commissioned by Trevisa's patron, Lord Berkeley. Written in Middle English, it consists of a series of arguments made by the clerk on why books should not be translated from learned languages such as Latin, each one followed by a rebuttal from the lord. The clerk eventually agrees, and the exchange concludes with a prayer for guidance in the translation. Source: Wikipedia (en)
