In order to understand this regular life the inquirer must know something of the offices and position of the various superiors and officials, and must understand the parts, and the disposition of the various parts, of the material buildings in which that life was led. Moreover, he must realise the divisions of the day, and the meaning of the regulations, which were intended to control the day’s work in general, and in a special manner, the ecclesiastical side of it, which occupied so considerable a portion of every conventual day. After the description of the main portion of the monastic buildings given in the last chapter, the reader’s attention is now directed to the officials of the monastery and their duties. In most Benedictine and Cistercian houses the superior was an abbot. By the constitution of St. Norbert for his White canons, in Premonstratensian establishments as in the larger houses of Augustinian, or Black, canons, the head also received the title and dignity of abbot. In English Benedictine monasteries which were attached to cathedral churches, such as Canterbury, Winchester, Durham and elsewhere, the superiors, although hardly inferior in position and dignity to the heads of the great abbeys, were priors. This constitution of cathedrals with monastic chapters was practically peculiar to this country. It had grown up with the life of the church from the days of its first founders, the monastic followers of St. Augustine. No fewer than nine of the old cathedral foundations were Benedictine, whilst one, Carlisle, belonged to the Canons Regular. Chester, Gloucester, and Peterborough, made into cathedrals by Henry VIII., were previously Benedictine abbeys.
