The Mirror of Justices, also known in Anglo-Norman as Le mireur a justices[1] and in Latin as Speculum Justitiariorum, is a law textbook[2] of the early 14th century, written in Anglo-Norman French and traditionally attributed to Andrew Horn (or Horne). The original manuscript is in the Parker Library, Corpus Christi College, Cambridge (manuscript identifier CCCC MS 258).[3]
The work was published in 1642, based on a copy owned by Francis Tate and the Cambridge manuscript.[4] In 1646 it was translated into English and printed together with Anthony Fitzherbert's The Diversity of Courts and their Jurisdictions. This version was republished in 1659[5] and 1768.[6] In 1895 the Selden Society published an edition of the work containing the Anglo-Norman text with a parallel English translation, and an extensive introduction by Frederic William Maitland.
