The Carthusians were a religious order instituted by Saint Bruno in 1084. He built several hermitages four leagues from Grenoble in south-east France, and, with six companions, united the ascetic with the monastic life. They practised the greatest abstinence, wore coarse garments, and ate only vegetables and the coarsest bread. From their original seat they were called Carthusians. Their fifth general, Guigo (died 1137), prescribed, besides the usual monastic vows, eternal silence and solitude. In the following centuries they received additional statutes, which forbade altogether the eating of flesh, and allowed them to speak only during certain hours on Thursdays and the days on which the chapter met. With increasing wealth some modifications were introduced in their silent and solitary life. Their habit is a hair-cloth shirt, a white tunic, a black cloak, and a cowl. The Carthusians were introduced into England about 1180, and built the Charterhouse (a name corrupted from Chartreuse) in 1371. Their chief house was long La Grande Chartreuse. Research Carthusians
