The Roman Catholic monastic order (also spelled Carthusian) was founded in 1084 by Bruno (1035-1101), who was later canonised, in La Chartreuse near Grenoble in France. The name Charterhouse (for monastery) is derived from the Latin term Cartusia for the place where the first Charterhouse was founded. The rules of the order are still today in a reduced form the strictest asceticism (fasting with bread, water and salt three times a week), the commandment of eternal silence (communication only by signs) and prayer (eight hours a day). The Order's motto is: Stat crux dum volvitur orbis (The cross stands firm while the globe keeps turning) . In the Middle Ages, the Carthusians owned extensive vineyards in Cahors in France, Switzerland, Trier on the Moselle in Germany and Priorato in Spain, among other places.
