These three laisses, that is, decasyllabic verse-paragraphs of various lengths whose lines end with the same assonance, are from the thirteenth-century Franco-Italian version of The Song of Roland, known as the V4 manuscript of St. Mark's Church, Venice. They illustrate creative thirteenth-century innovations, in a slightly different language, added to the much better known twelfth-century Anglo-Norman French Chanson de Roland, known as the Oxford version.
