may be removed by him at any time. In many monasteries, especially larger ones, the claustral prior is assisted by a sub-prior, who holds the third place in the monastery. In former times there were in larger monasteries, besides the prior and the sub-prior, also a third, fourth and sometimes even a fifth prior. Each of these was called circa (or circator), because it was his duty to make the rounds of the monastery to see whether anything was amiss and whether the brethren were intent on the work allotted to them respectively. He had no authority to correct or punish the brethren, but was to report to the claustral prior whatever he found amiss or contrary to the rules. In the Congregation of Cluny and others of the tenth, eleventh and twelfth centuries there was also a greater prior (prior major) who preceded the claustral prior in dignity and, besides assisting the abbot in the government of the monastery, had some delegated jurisdiction over external dependencies of the abbey. In the high days of Cluny, the abbot was assisted by a coadjutor styled Grand-Prior (Grand-prieur in French). The Conventual prior (Latin prior conventualis) is the independent superior of a monastery that is not an abbey (and which is therefore called a "priory"). In some orders, like the Benedictines, a monastery remains a priory until it is considered stable enough and large enough to be elevated to the rank of an abbey. In other Orders, like the Camaldolese and Carthusians, conventual priors are the norm and there are no abbots. (The superior of the major houses of Camaldolese nuns, however, is called an abbess.) This title, in its feminine form prioress, is used for monasteries of nuns in the Dominican and Carmelite orders. An Obedientiary Prior heads a monastery created as a satellite of an abbey. When an abbey becomes overlarge, or when there is need of a monastery in a new area, the abbot may appoint a group of monks under a prior to begin a new foundation, which remains a dependency of the mother abbey until such time as it is large and stable enough to become an independent abbey of its own. A Prior Provincial is the regional superior of certain Orders, such as the Order of Friars Preachers Dominicans or the Carmelite friars. In this last case, the head of the whole Order is called the
