Marco Nievergelt studied at the Universities of Lausanne, Glasgow, and Oxford.

His research specializations include allegorical poetry, the relations between medieval literature and philosophy, chivalric literature and romance, Anglo-French cultural and literary relations, and medieval translation. He is currently a Marie Curie Post-Doctoral Fellow at the EPHE/PSL in Paris, working on a research project on the Science, Philosophy, and Poetics of Experience in Late Medieval England (SPPELME).

• Introduction I. Jean de Meun 1: In the Beginning was the Rose II. Deguileville Introduction to Part II 2: Language 3: Cognition: Theory and Practice 4: Experience III. Langland Introduction to Part III 5: The Desire for Knowledge and the Experience of Conversion 6: The Experience of Failure and the Architecture of Vision 7: The Ends of Experience: Incarnation and Apocalypse

Nievergelt's book is long, challenging, and deeplyrewarding. Whatever position readers might take on the many arresting arguments advanced here, anyone who reads Medieval Allegory as Epistemologycannot fail to be convinced of the intellectual richness of the Rose, the dynamism and interest of Deguileville's writing, and the huge importance of these works for understanding the cultural landscape that Langland inhabited.
