Mark Antony de, archbishop of Spalatro in Dalmatia at the close of the 15th and beginning of the 16th centuries, was a man whose sicknessness in religion proved his ruin. His preferment, instead of attaching him to the church of Rome, rendered him disaffected to it. Becoming acquainted with our Bishop Bedell, while chaplain to Sir Henry Wotton, ambassador from James I. at Venice, he communicated his books *De Republica Ecclesiastica* to him; which were afterwards published at London, with Bedell's corrections. He came to England with Bedell; where he was received with great respect, and preached and wrote against the Romish religion. He is said to have had a principal hand in publishing Father Paul's *History of the Council of Trent*, at London, which was inscribed to James in 1619. But on the promotion of Pope Gregory XIV. who had been his schoolfellow and old acquaintance, he was deluded by Gondomar the Spanish ambassador into the hopes of procuring a cardinal's hat, by which he fancied he should prove an instrument of great reformation to the church. Accordingly he returned to Rome in 1622, recanted his errors, and was at first well received; but he afterwards wrote letters to England, repenting his recantation; which being intercepted, he was imprisoned by Pope Urban VIII. and died in 1625. He was also the author of the first philosophical explanation of the rainbow, which before his time was regarded as a prodigy.
