Celestines were a
Roman Catholic monastic order, a branch of the
Benedictines, founded in 1244. At the foundation of the new rule, they were called
Hermits of St Damiano, or Moronites (or Murronites), and did not assume the appellation of Celestines until after the election of their founder, Peter of Morone (Pietro Murrone), to the
Papacy as
Celestine V.
