CAMALDUNIANS, or Camaldolites, an order of religious persons, founded by Romuald, an Italian, in 1023, in the desolate waste of Camaldoli, or Campo Mahuli, on the lofty heights of the Apennines. Their rule is that of St Benedict; and their houses, by the statutes, can never be less than five leagues from cities. They are divided into conobites and eremites. The Camaldulians, till the close of the eleventh century, were called Romualdins; previously, Camaldulian was a particular name for those of the desert Camaldoli. Guido Grandi, a Camaldulian monk, and mathematician to the grand duke of Tuscany, published Camaldulian Dissertations on the origin and establishment of this order.
