What is the X in X-mas?
leading medieval English jurist and author of De legibus et consuetudinibus Angliae (c. 1235; "On the Laws and Customs of England"), one of the oldest systematic treatises on the common law. While depending chiefly on English judicial decisions and the methods of pleading required by English judges, Bracton enlarged the common law with principles derived from both Roman (civil) law and canon law. De legibus shows the influence of several European continental jurists-notably Azzone (Azo), a Bolognese glossator of Roman law-and its style suggests that he was trained at Oxford, which then was the centre for the study of civil law in England. Bracton's work did not have a lasting impact on studies of the common law on the European continent, a fact indicative of the comparative unimportance of systematic scholarly exposition of the common law.
