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. 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. 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. Fioretti likewise was known as a sort of wonderworker who worked miracles during his lifetime. He was also known for his warm sense of humor and his simple method for living.
