Pretenders to royal honours seldom acquire the grace of genuine royalty, and the Cardinal pursued with vindictive ferocity those who offended his sensitive dignity. In 1515, Polydore Vergil said, in writing to his friend, Cardinal Hadrian, that Wolsey was so tyrannical towards all men that his influence could not last, and that all England abused him.[300] The letter was copied by Wolsey's secretary, Vergil was sent to the Tower,[301] and only released after many months at the repeated intercession of Leo X. His correspondent, Cardinal Hadrian, was visited with Wolsey's undying hatred. A pretext for his ruin was found in his alleged complicity in a plot to poison the Pope; the charge was trivial, and Leo forgave him.[302] Not so Wolsey, who procured Hadrian's deprivation of the Bishopric of Bath and Wells, appropriated the see for himself, and in 1518 kept Campeggio, the Pope's legate, chafing at Calais until he could bring with him the papal confirmation of these measures.[303] Venice had the temerity to intercede with Leo on Hadrian's behalf; Wolsey thereupon overwhelmed Giustinian with "rabid and insolent language"; ordered him not to (p. 113) put anything in his despatches without his consent; and revoked the privileges of Venetian merchants in England.[304] In these outbursts of fury, he paid little respect to the sacrosanct character of ambassadors. He heard that the papal nuncio, Chieregati, was sending to France unfavourable reports of his conduct. The nuncio "was sent for by Wolsey, who took him into a private chamber, laid rude hands upon him, fiercely demanding what he had written to the King of France, and what intercourse he had held with Giustinian and his son, adding that he should not quit the spot until he had confessed everything, and, if fair means were not sufficient, he should be put upon the rack".[305] Nine years later, Wolsey nearly precipitated war between England and the Emperor by a similar outburst against Charles's ambassador, De Praet. He intercepted De Praet's correspondence, and confined him to his house. It was a flagrant breach of international law. Tampering with diplomatic correspondence was usually considered a sufficient cause for war; on this occasion war did not suit Charles's purpose, but it was no fault of Wolsey's that his fury at an alleged personal slight did not provoke hostilities with the most powerful prince in Christendom.[306] [Footnote 300: _L. and P._, ii., 215.] [Footnote 301: _Ibid._, ii., 491, 865, 1229.] [Footnote 302: _Ibid._, ii., 3581, 3584; _Ven.
