In 1609-1610 he was involved in discussions with
Henry Wotton, Sarpi and Johann Baptist Lenk, acting in Venice for
Christian of Anhalt. He had preached carefully scripted sermons, composed with
William Bedell. He was then embarrassed by a diplomatic leak concerning the visit of
Giovanni Diodati: Wotton on the advice of Sarpi and Micanzio had invited him to Venice in 1607. Some redacted correspondence of Diodati to a French recipient was passed to the Venetian authorities by the French ambassador in 1609, representing Micanzio as a Trojan horse for Protestantism in Venice. He was then forbidden to preach. Micanzio took extensive notes on the
Annales Ecclesiastici of
Baronius. He with Sarpi looked to undermine the version of church history represented by the approach taken by Baronius. This put them on a track parallel to the scholars at work in England, particularly
Isaac Casaubon, taking aim at the historiography favoured by the
Roman Curia.
John Donne's will included a pair of portraits of Sarpi and Micanzio. Micanzio had an abiding reputation as an
Anglican sympathiser, being mentioned for example (as "Father Fulgentio") in
Samuel Johnson's essay on Sarpi as "administering to Dr. Duncomb, an English gentleman that fell sick at Venice, the communion in both kinds, according to the Common Prayer, which he had with him in Italian".
Eleazar Duncon is known to have had conversations with Micanzio at Venice around 1648. ==Later life==
