Crispino da Viterbo (13 November 1668 – 19 May 1750) - born Pietro Fioretti - was an Italian Roman Catholic professed religious from Order of Friars Minor Capuchin.

[1] Fioretti was an ardent devotee of the Mother of God and was consecrated to her protection in 1674 and he even made a small altar dedicated to her when he served in the kitchens at the house in Orvieto.

[2][3] He served in various roles for the order in various cities around Rome where he became a well-known figure with various nobles and prelates - even Pope Clement XI visiting him and seeking him out for advice and support.

[2] He knew Cardinal Filippo Antonio Gualtieri who was one such prelate who liked to meet and speak with Fioretti on a number of occasions.

In Orvieto he lived on the first floor in a small room and he rose in the morning to meditate before he attended a number of Masses.

Illustrious individuals visited the simple friar including bishops and cardinals and even Pope Clement XI himself who took great delight in conversing with the humble Franciscan (the two would also meet sometimes at Castel Gandolfo).

[2] It was his constant endeavor to imitate the virtues of his patron Felice di Cantalice whom he had chosen as his model of perfection at the beginning of his religious life.

[1][4] His remains - at present in a state of remarkable preservation - rests under one of the side altars in the famed Santa Maria della Concezione dei Cappuccini church in Rome.

[6] The miracle that led to his canonization was investigated in the diocese it originated in from 1958 to 1960 before the Congregation for the Causes of Saints validated that process on 18 March 1977.

alone met and approved the case on 21 March 1979 before presenting it to Pope John Paul II who recognized the healing of Rinaldo Crescia on 21 May 1950 was a miracle from Fioretti's intercession.
