Carmen de Prodicione Guenonis ("Song of the Treachery ofGanelon") is an anonymous poem in medieval Latin, written in the first half of the 12th century. Composed in elegiac couplets by an unskilled versifier, it is a version of the legendary history of theBattle of Roncevaux Pass. This is the same story that is told in the Old FrenchChanson de Roland and in several other versions and languages. The Latin poem seems to be based on a hearing or reading of an Old Frenchchanson de geste, in the same tradition as the writtenChanson but differing from it in many details, perhaps around the year 1120.
