an Italian ecclesiastic, flourished in the first half of the 17th century. Sent by pope Urban VIII to England, he remained there from 1634 to 1636, in order to reconcile the differences which had arisen among the Roman Catholics. On his return home he was made canon of St. Lorenzo at Rome, and bishop of Miletus in partibus. He wrote some interesting memoirs upon the mission, but they have never appeared in separate form. Dodd has inserted some extracts in his History of the Church, and an English priest, Joseph Berington, published a translation of them, entitled Memoirs of Gregorio Panzani (Birmingham, 1794, 4to).
