What is "quadripartitus"

The title Quadripartitus refers to an extensive legal collection compiled during the reign of Henry I, king of England (1100–1135). The work consists of Anglo-Saxon legal materials in Latin translation as well as a number of Latin texts of legal interest that were produced after the Conquest. It ranks as the largest surviving medieval collection of pre-Conquest law and is the second to have been produced during Henry I's reign, after that contained in Cambridge, Corpus Christi College MS 383. First compiled for the use of Henry I's jurists and administrators, the Quadripartitus enjoyed immense interest for a considerable time afterwards and was consulted by legal scholars, including Henry de Bracton in the thirteenth century and John Fortescue in the fifteenth.
