Bracton imbued the courts of his day with a broad, Continental or cosmopolitan outlook. The incorporation of Roman Law began with Ranulf de Glanvill 140 years before. This is demonstrated in "Leges Henrici Primi" (Laws of Henry I). There is some controversy about the true nature of Bracton's Romanism. Henry Maine regarded Bracton as a complete fraud, who tried to pass off sheer Romanism as legitimate English law. For this, in his view, Bracton should be completely dismissed as a figure of substance in the formation of English law. Frederic William Maitland held the opposite view, positing that Bracton had no real knowledge of Roman law, and the portion which he did proclaim was incomplete and shallow. These were of the opinion that most, if not all the Romanism of Bracton was derived directly from Azo of Bologna, written before 1211. It has proven to be difficult to pinpoint the exact nature of Romanism in Bracton.
