Ordained in 1634, he took the religious name Bonaventure. Around 1651 he left Rome, and went first to a house of his Order at Schwaz in Tyrol, and then to Salzburg, where he was kindly received by Archbishop Guidobald. He was sent as commissary into Habsburg Hungary (about 1656), was again in Schwaz (1661), went to Paris, taught for some time at Würzburg, where he published a volume of his "Opuscula" (1668), taught theology at Lyon in southern France and finally returned to Italy. It is said that representations were made to secure his appointment to the Archbishopric of Cashel, but that he declined the office. He was appointed historiographer in 1676 by Cosmo I de' Medici, Grand-duke of Tuscany and was elected a member of the Academy of Florence.
