On the curious subjects of knighthood, knights-service, nobility, arms, cry of war, banners, and tournaments, an ample fund of information may be sought in Selden (Opera, tom. iii. part i. Titles of Honor, part ii. c. 1, 3, 5, 8), Ducange (Gloss. Latin. tom. iv. p. 398 - 412, etc.), Dissertations sur Joinville (i. vi. - xii. p. 127 - 142, p. 161 - 222), and M. de St. Palaye (Memoires sur la Chevalerie).
