Chanson de Guillaume
The Chanson de Guillaume, also called Chançun de Willame (English: "Song of William"), is a chanson de geste from the first half of the twelfth-century (c. 1140, although the first half of the poem may date from as early as the eleventh century; along with The Song of Roland and Gormont et Isembart, it is considered one of three chansons de geste whose composition incontestably dates from before 1150). The work is generally considered to have two distinct halves: the first tells of Guillaume of Orange, his nephew Vivien and the latter's young brother Gui and their various battles with Saracens at L'Archamp; in the second half of the poem (after 2000 lines), Guillaume is aided by Rainouard, a giant.
