The Carmen de bello Saxonico (German: Lied vom Sachsenkrieg; English: Song of the Saxon War) is a Latin epic in 757 hexameters divided between three books that recounts the first phase of the Saxon Rebellion against the Emperor Henry IV that began in 1073.
It is strongly pro-imperial in tone, and complements the pro-Saxon histories of Bruno the Saxon and Lambert of Hersfeld.
It was composed within months of the events it describes, but the only existing manuscript copy dates from the sixteenth century.
The anonymous author made use of several classical writers, including Virgil, Horace, Lucan, Ovid and Sedulius.
His familiarity with local geography hints that he may have been a royalist Saxon, like the Poeta Saxo of two centuries earlier.
