286 THE ROAD TO FREEDOM everywhere we find the lord only willing to allow just so much as suits his purpose. The serf's aspirations mean little or nothing to him. While all this was going on the lawyers were far from certain about their law. Glanvill (c. 1187) lays down his view in some detail.1 He says that a serf is unable to buy his freedom, since he has nothing but what belongs eventually to his lord. "Hence, if the latter liberates him in consideration of a sum of money then a difficulty arises; this is met by the intermediation of a third person who purchases the serf nominally with his own, though really with the serf's money ".2 Glanvill seems to imagine that a lord can manumit his serf so as to make him free as regards himself, while he remains still a serf as regards all other men. The whole conception is puzzling, and neither Vinogradoff nor Pollock and Maitland have been able to clear up the involved law as stated by Glanvill.3 By Bracton's time (c. 1250), how- ever, things had changed, and he reports cases of serfs buying their freedom with their own money,4 although the older prac- tice was still known. The law on the subject was still fluid; and, as Vinogradoff has pointed out, "Everything seems in a state of vacillation and fermentation during the thirteenth century".5 Besides difficulties arising from these straightforward types of manumission medieval lawyers wrangled a great deal over certain actions which, as some held, carried with them a recognition of free status. Of these the most important was whether by entering into an agreement with a serf his lord confers freedom on him: by treating him as a free man does he make him free? Vino- gradoff points out that "the line between covenant and enfran- chisement was so easily passed, and an incautious step would have such unpleasant consequences for landlords, that they kept as clear as possible of any deeds which might destroy their claims as to the persons of their villeins".6 Nevertheless, instances can 1 Op. dt.
