This _Castilian_, nam'd _Sancho_, was a Creature of the Duke of _Medina Sidonia_'s, and, before the late Revolution, Pay-Master of the _Spanish_ Army in _Portugal_. He, with the rest of his Countrymen who were taken up at that time, groan'd in Confinement, nor had they any prospect of Liberty; but hearing of this Monk, and being inform'd of his Country, his extravagant Conduct, his Credit at Court, and several other Circumstances, which made it plain that he was there employ'd in some secret Business; he thought he had now an opportunity of obtaining his Liberty, and with this hope he wrote the Monk a long Letter, full of Expressions fit to sooth his Vanity; in it he complain'd, that the King of _Portugal_ detain'd him in Prison, (with the other _Castilians_) who was a Servant and Creature of the Duke his Brother-in-law: and to confirm it, he sent him several Letters, wrote to him by that Prince himself some little time before the Revolution, in which he treated him as one in whom he repos'd an entire Confidence. The _Franciscan_ answer'd _Sancho_'s Letter, and assur'd him, that nothing could recommend him more to him, than his belonging to the Duke of _Medina_; that he would use all his endeavour to procure him his Liberty, but in the mean time he must take care not so much as to open his mouth about it. The _Spaniard_ waited some days for the Effect of his Promise, and at last sent him a second Epistle, in which he represented, that seven Months were expir'd since he was cast into Prison; that the _Spanish_ Minister seem'd to have quite forgotten him, since he neither talk'd of ransoming or exchanging him; and that therefore he had no hopes of Liberty left, but what were built upon the Charity and Interest of the Reverend Father. The Monk, who thought he should very much oblige the Duke of _Medina_, by procuring _Sancho_ his Freedom, begg'd it of the King, and obtain'd it. He went to the Prison himself, to fetch him out of it, and offer'd to have him included in a Passport, which was to be given to some of the Dutchess of _Mantua_'s Servants, who were then returning to _Madrid_. But the crafty _Castilian_ answer'd him, that _Madrid_ was a Place to which he could never more return; that he must not pretend to appear at Court, unless he desir'd to be thrown into Prison again, seeing that _Olivarez_ was so severe and unjust, that he would expect his Accounts to be made up, altho in the late Revolution he had been stript not only of his Money, but had had his Books also taken from him: To this he added, that he desir'd nothing more than to be near the Duke of _Medina_, his Patron, who was both able and willing, he did not question, to advance him.
