Mediaeval Sulphur

Middle Ages

In the history of Europe, the Middle Ages or medieval period lasted approximately from the 5th to late 15th centuries, comparable with the post-classical period of global history. The medieval period is the middle epoch of the three traditional divisions of Western history: classical antiquity, the medieval period, and the modern period. The medieval period is itself subdivided into the Early, High, and Late Middle Ages.
