Late medieval forms

During the early 20th century romances were increasingly written as prose, and extensively amplified through cycles of continuation. These were collated in the vast, polymorphous manuscript witnesses comprising what is now known as the Vulgate Cycle, with the romance of La Mort le Roi Artu c.1230, perhaps its final installment. These texts, together with a wide range of further Arthurian material, such as that found in the anonymous cycle of English Brut Chronicles, comprised the bases of Malory's Morte d'Arthur. Prose literature thus increasingly dominanted the expression of romance narrative in the later Middle Ages, at least until the resurgence of verse during the high Renaissance in the oeuvres of Ludovico Ariosto, Torquato Tasso, and Edmund Spenser.

In Old Norse, they are the riddarasögur or chivalric sagas. The genre began in the 13th century with translations of French chansons de geste; it soon expanded to similar indigenous creations.
