Bonaventura. The parents of S. Bonaventura were Giovanni di Fidanze and Maria Ritella. He was born at Bagnorea, near Viterbo, in 1221, and baptized Giovanni. This was changed to Bonaventura owing to the exclamation of S. Francis, O buona ventura, when the child was brought to him to be cured of a dangerous illness. (This account has been doubted, and it is true that others bore the name before S. Bonaventura.) S. Bonaventura was canonized by Sixtus IV, 14 April, 1482. This formal enrolment in the catalogue of the Saints was thus long delayed mainly owing to the unfortunate dissensions concerning Franciscan affairs after the Saint's death, 15 July, 1274. He was inscribed among the principal Doctors of the Church by Sixtus V, 14 March, 1587. His feast is celebrated 14 July.
