The Mirror of Justices, also known in Anglo-Norman as Le mireur a justices[3] and in Latin as Speculum Justitiariorum,[4] is a law textbook[5] 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).
[6] The work was published in 1642,[1] based on a copy owned by Francis Tate and the Cambridge manuscript.
[7] In 1646 it was translated into English and printed together with Anthony Fitzherbert's The Diversity of Courts and their Jurisdictions.
[9] 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.
