Which types of literary works were written in Anglo-Norman?

Anglo-Norman literature, which flourished in medieval England from the 12th to the 15th century, encompassed a wide variety of genres. While the chanson de geste was notably absent as an original form, most other literary types were well-represented.1

Key categories of Anglo-Norman works include:

• Religious and Didactic Writings: This includes biblical translations (such as the "Book of Kings" and the Psalter), saint biographies, and an extensive collection of doctrinal and devotional texts for the laity. It also features the earliest plays in French, such as the Mystère d’Adam, and numerous technical treatises on law, medicine, agriculture, grammar, and science.1
• Romances: Anglo-Norman writers produced significant courtly romances, including versions of the Tristan story and the Alexander romance, as well as original tales like Waldef.1
• Lais and Fabliaux: Notable works include the narrative lays and fables by Marie de France, which blended fairy-tale elements with realistic social observation.1
• Historical and Political Writings: This category includes chronicles, such as the Estoire des Engleis, political songs, and biographies of prominent figures like William Marshal.1
• Scientific Works: Authors like Philippe de Thaon wrote early bestiaries and works on natural history.1
