Acta et Diplomata Graeca Medii Aevi Sacra et Profana 6 Volume Set

This six-volume work, published between 1860 and 1890, contains a selection of documents in Greek which throw light on the history and politics of the Byzantine Empire in the Middle Ages. The editors, Franz Miklosich (1813-91), philosopher, linguist and Slovenian nationalist, and Josef (or Giuseppe) Muller (1823-95), a Greek scholar who also translated many important works by German classical historians into Italian, used as one of their sources the volumes of Greek manuscripts brought back to Vienna by Ogier Ghiselin de Busbecq (1522-92), the Flemish diplomat, herbalist, and travel writer who had acted as Imperial Ambassador to the Sublime Porte. Volumes 1 and 2 contain decrees of the Patriarchs of Constantinople between 1315 and 1402; Volume 3 consists of documents concerned with the relations of the Empire with the Italian cities; and Volumes 4-6 contain founding charters and other documents relating to Orthodox monasteries and churches.
