Being fully confirm'd in this Resolution, he began to think of the speediest Means of putting it in execution, well knowing that he should not long enjoy the Place of President of the Palace, which was not as yet taken from him. He plainly saw that it was in vain to follow the King's Measures, by endeavouring to win the People, and make them join with him; their Hatred to the _Spaniards_ being too deeply rooted in their Hearts. The Nobility, he was assur'd, wou'd not assist him, since by their means the Crown was placed upon the Duke of _Braganza_'s Head: he could therefore only depend upon the Grandees, who with envy beheld one that had been their Equal, upon the Throne. The first thing he did, was to assure himself of _Olivarez_'s Protection and Assistance: after which, he began to work upon the Marquiss of _Villareal_; to whom he represented, that the new King was timorous and diffident, for which reason he sought all opportunities of ruining his Family, lest he should leave a Subject who was capable of disputing the Crown with his Successor: That he and the Duke _d'Aveiro_, who were both of the Royal Blood, were not thought worthy of any Office or Employment; whilst all Places of Trust were fill'd by a company of factious and seditious People: That with indignation the People saw how little he was valued, and were very much troubled to think that a Person of his Quality and Capacity must spend his time at a Country-Seat, and in an inglorious Ease: That one of his Birth and Estate was too great to be the Subject of so petty a Prince as the King of _Portugal_: That he had lost a Master in the King of _Spain_, who only was capable of bestowing such Employments on him as he deserv'd, by reason of the many Kingdoms of which he was Sovereign, and over which he must establish Governours. Seeing that this Discourse made an impression on the Mind of the Marquiss, he went so far as to assure him, that he had Orders from the King of _Spain_ to promise him the Viceroyalty of _Portugal_, as a Reward of his Loyalty, in case he would assist him in his Design of recovering that Kingdom. Notwithstanding what the Archbishop promis'd, the thing was very far from his Heart; his chief Aim being to restore the Dutchess of _Mantua_ to her Liberty and former Authority: for the compassing of which, he thought it very lawful to promise what he never intended to perform; and he knew that ambitious Motives were the likeliest to engage the Marquiss _de Villareal_, upon whom his fair Speeches had at last such an effect, that he yielded to his Persuasions, and promis'd that he, with his Son the Duke of _Camino_, would be at the head of the Enterprize.
