The Leges was written between 1114 and 1118 by an unknown Norman, who is very likely to be the author of another legal work, the Quadripartitus,[REF] although some historians, including H. G. Richardson and G. O. Sayles, argue that the two works were by different authors [REF].
Usually the work has been known as the Leges Henrici Primi, or Laws of Henry the First.
