This authoritative reference work covers medieval European history, culture, religious and intellectual life, and technology, 400-1500 AD. It is an English translation of the 2013 update of the well-known German-language Enzyklopädie des Mittelalters, which was originally published by Primus Verlag / Wissenschaftliche Buchgesellschaft in 2008.
Transnational and interdisciplinary in approach, topics cover current art and architecture, medicine, and law, archaeology, ecclesiastical history, and languages and literature. They focus not on event history but on the comparative study of wider processes and problems.
