The Carthusian Order, also called the Order of [[Saint Bruno]], is an enclosed Christian religious Roman Catholic Order founded by [[Saint Bruno]] in [[1084 AD|1084]]. There exist both Carthusian monks and nuns. They follow their own Rule, called the Statutes, rather than the [[Rule of Benedict]] (as is often erroneously reported) and combine eremitical and cenobitic [[monasticism|monastic]] life.
The motto of the Carthusians is "Stat crux dum volvitur orbis" meaning "The Cross is steady while the world is turning". The name 'Carthusian' is derived from Chartreuse, a French valley in the Alps which was where Saint Bruno built his first hermitage. The word 'Charterhouse', which is the English name for a Carthusian monastery, is derived from the same source.
