chansons de geste, epic poems in Old French embodying legends which had grown up about earlier historical figures. The earliest extant versions are from the 12th cent. and use the legends to embody problems and difficulties of feudal society: either the stresses within the feudal system itself caused by conflicting loyalties, as in
Raoul de Cambrai and
Girart de Roussillon; or those caused by the impact of the Crusades on feudalism, as in the
Chanson de Guillaume and, above all, in the
Chanson de Roland (see
Roland). These epics gradually grew into three cycles, first delineated by Bertran de Bar-sur-Aube, a writer of two such poems in the early 13th cent.: firstly, the
geste du roi, those dealing with the
Charlemagne of legend and his knights; secondly, those dealing with Charlemagne's rebellious vassals, the
geste de Doon de Mayence; and thirdly, the William of Orange cycle, the
geste de Garin de Monglane. The genre followed the usual development of narrative literature during the Old French period: the earliest poems, the
Roland and
Gormont and Isembart, are heroic; the 12th-cent. poems, with William of Orange as their hero, are more realistic; the later poems have courtly and marvellous elements in them, and lose the tragic seriousness of the earlier works. Similarly, the later ones become more elaborate in style, while the early poems were written in a simple, formulaic style of great dramatic force. The only parallel English poems are those concerned with Charlemagne, such as the fragmentary Middle English
Song of Roland (see
Ferumbras and
Otuel).
