Sommario/riassunto

Chemistry and chemical technology have been at the heart of the revolutionary developments of the 20th century. The chemical industry has a long history of combining theory (science) and practice (engineering) to create new and useful products. Worldwide, the process industry (which includes chemicals, petrochemicals, petroleum refining, and pharmaceuticals) is a huge, complex, and interconnected global business with an annual production value exceeding 4 trillion dollars. Although in industry special focus is in heterogeneous catalysis, homogeneous, enzymatic, photochemical and electrochemica

Sommario/riassunto

Die vorliegende Arbeit beschäftigt sich mit Quellen zur Geschichte der Bistümer Reims und Trier seit dem 8. Jahrhundert. Am Anfang stehen wesentliche Angaben zur Geschichte dieser Bistümer im frühen Mittelalter, die hauptsächlich auf Nachrichten des einflussreichen Reimser Erzbischofs Hinkmar (845-882) zurückgehen. In der Folge



vielfach rezipiert, prägen sie bis heute nachhaltig Überlieferung und Forschungsstand zu beiden Orten. Im Zentrum der Untersuchung stehen ein Reimser Königsgrab und der vermeintliche Bischof Milo, der beide Metropolen längere Zeit gemeinsam innegehabt haben soll. Doch das kirchenrechtlich nur schwer zu begründende Doppelamt und die über mehrere Jahrhunderte gestreuten Zeugnisse weisen erhebliche Widersprüche auf, die man bislang zu einem stimmigen Gesamtbild zu harmonisieren suchte. Hinkmars Ausführungen sowie ihr Fortwirken bilden deshalb den Gegenstand dieser Arbeit. Es gilt, sie sowohl vor dem zeitgenössischen Hintergrund ihrer Abfassungszeit zu problematisieren als auch ihre späteren Verformungen durch die Zeit zu verfolgen. Nimmt man die Spur dieser Verformungen auf, so wird die Kontingenz historischer Nachrichten und Überlieferung deutlich. Von Reims führt ihr Weg bald nach Trier und von dort weiter zu den benachbarten Klöstern Echternach und Mettlach.
