The general observations on items in this section in the 1976 Bibliography still hold by and large. Genre has been added because of the increase in the number of publications devoted to the topic, with respect both to Chrétien and to romance writing in the twelfth and thirteenth centuries. Questioning received opinion has been on the rise – for example, whether Perceval is incomplete or whether Godefroi de Lagny actually wrote the last thousand lines of the Charrette. Much of this reflects greater uncertainty about composition in earlier periods, an uncertainty that allows for greater latitude to test or question received or authoritative interpretations. Similarly, there is less agreement on which social or moral standards Chrétien may actually have fostered in his romances, and more emphasis on perceived problematic or debatable implications of his narratives (He55). Matters of intertextuality (see L) have made his relations with other romances or other works a growing factor in interpretation, and this is likely to continue as interest grows in his influence on subsequent French writing (see Pa). As the crossreferences suggest, interpretation is often influenced more by diverse modern methodologies and theoretical positions (U) than by earlier, medieval conceptions (F).
