De planctu naturae
Alan of Lille (1120–1202)
Alan of Lille's De planctu naturae ("The Complaint of Nature") is a twelfth-century Latin prosimetrum in which personified Nature laments human disorder and the misuse of sexuality and language. Probably composed around the 1160s–1170s, it joins Boethian consolation, Chartrian cosmology, Christian moral critique, and elaborate rhetoric. Its allegory helped shape later medieval representations of Natura, especially Jean de Meun's continuation of the Roman de la Rose and the tradition that reaches Chaucer. Schola presents the Latin text with an English translation.
