(Latin camerarius).
The title of certain papal officials. The Low Latin word camera (chamber) means the treasure of the prince, monastery, etc.; also in general the royal treasury (fiscus), the temporal administration of a monastery. The term camerarius was, therefore, very frequently equivalent to civil treasurer, and in the case of monasteries meant the monk charged with the administration of the monastic property. This is also the sense of the Italian term camerlengo, still borne at Rome by three ecclesiastics, (1) The Camerlengo of the Holy Roman Church, (2) the Camerlengo of the Sacred College (of Cardinals), and (3) the Camerlengo of the Roman Clergy. The Roman confraternities have also an officer similarly entitled.
