4 o6 THE HISTORY OF MEDIEVAL EUROPE singers, however, was found perhaps the greatest of all medieval lyric poets, Walther von der Vogelweide (Walter of Bird-Meadow). From the south we turn back again to the north of France to consider other varieties of literature which developed The courtly there a little later than the chansons de geste. By e P ic the latter part of the twelfth century the south- ern court life and higher regard for woman began to affect the northern epics, especially since actual social conditions in the north also were growing more settled and refined. Consequently the courtly epic of the thirteenth century, with its glorification of love and ladies, became quite dif- ferent from the twelfth-century chansons de geste.
