That nuncio had gone to Barcelona to negotiate an alliance between the Pope and the Emperor; and the success of his mission completed Clement's conversion. The revocation was only delayed, thought Charles's representative at Rome, to secure better terms for the Pope.[647] On 21st June, the French commander, St. Pol, was utterly defeated at Landriano; "not a vestige of the army is left," (p. 226) reported Casale.[648] A few days later the Treaty of Barcelona between Clement and Charles was signed.[649] Clement's nephew was to marry the Emperor's natural daughter; the Medici tyranny was to be re-established in Florence; Ravenna, Cervia and other towns were to be restored to the Pope; His Holiness was to crown Charles with the imperial crown, and to absolve from ecclesiastical censures all those who were present at, or consented to, the sack of Rome. It was, in effect, a family compact; and part of it was the quashing of the legates' proceedings against the Emperor's aunt, with whom the Pope was now to be allied by family ties. "We found out secretly," write the English envoys at Rome, on the 16th of July, "that the Pope signed the revocation yesterday morning, as it would have been dishonourable to have signed it after the publication of the new treaty with the Emperor, which will be published here on Sunday."[650] Clement knew that his motives would not bear scrutiny, and he tried to avoid public odium by a characteristic subterfuge. Catherine could hope for no justice in England, Henry could expect no justice at Rome. Political expediency would dictate a verdict in Henry's favour in England; political expediency would dictate a verdict for Catherine at Rome. Henry's ambassadors were instructed to appeal from Clement to the "true Vicar of Christ," but where was the true Vicar of Christ to be found on (p. 227) earth?[651] There was no higher tribunal. It was intolerable that English suits should be decided by the chances and changes of French or Habsburg influence in Italy, by the hopes and the fears of an Italian prince for the safety of his temporal power. The natural and inevitable result was the separation of England from Rome. [Footnote 647: _Ibid._, iv., 154.] [Footnote 648: _L. and P._, iv., 5705, 5767; _cf. Sp.

Another detail was the excommunication of Zapolya, the rival of the Habsburgs in Hungary--a step which Henry VIII. denounced as "letting the Turk into Hungary" (_L. and P._, v., 274).] [Footnote 651: _L. and P._, iv., 5650, 5715.] CHAPTER IX.
