Aliscans is a chanson de geste of the late twelfth century.
It recounts the story of the fictional battle of Aliscans (Alescans), a disastrous defeat of a Christian army by a Saracen army.
It is dated, probably, as composed 1180–1190, and survives in 13 manuscripts.
It is generally thought to be a source for the Willehalm of Wolfram von Eschenbach, and the two works cover the same events.
[1] The chanson is likely based on the Chançun de Willame, a version of the cycle from the beginning of the century.
