So violent was the Passion of the Archbishop, that he was not asham'd to make use of the profess'd Enemies of _Jesus Christ_, to drive a _Christian_ Prince from a Throne, which rightfully belong'd to him; and this was perhaps the first time that ever the Inquisition and Synagogue went hand in hand together. Several Schemes were propos'd, but at last this, which was drawn by the Archbishop, and approv'd of by the first Minister of _Spain_, was agreed upon; That the _Jews_ should set fire to the four Corners of the Palace on the 5th of _August_, and at the same time to several Houses both in the City and Suburbs, that the People might every where be employ'd in extinguishing the Fire; that the Conspirators should all fly to the Palace under pretence of assisting, and that amidst the Horrour and Confusion which this vast Conflagration would cause, some of them should assassinate the King; that the Duke _de Camino_ should seize the Queen and her Children, who might be as serviceable to them in regaining the Citadel, as the Dutchess of _Mantua_ had been to their Enemies; that at the same time there should be Fireworks ready to be play'd off, to set the _Portuguese_ Fleet on fire; that the Archbishop, with the Grand Inquisitor and all his Officers, should march thro the Town, to keep the People in awe, and prevent their coming to the Assistance of the King, so much do they dread the Power of the Inquisition; and that the Marquiss _de Villareal_ should take the Administration upon him, till they had receiv'd Orders from the Court of _Spain_. But as they had not the least reason to hope that the People would second them, they thought it necessary to make sure of some Troops, and to that end wrote to _Olivarez_ to send a Fleet towards the Coasts of _Portugal_, which should be ready to enter the Port of _Lisbon_ at the time when the Conspiracy should break out; and that there should be some Forces on foot on the Frontiers of the Kingdom, which should be in a readiness to act against any Place, which would not willingly surrender to the King of _Spain_. But the most difficult part of their Labour was to keep an exact Correspondence with the _Spanish_ Minister: for since the King had been inform'd that the Dutchess of _Mantua_ had sent Letters to _Madrid_, there was such a strict Guard kept upon the Frontiers of the Kingdom, that no one could go into _Castile_ without the King's own Passport; nor did they dare attempt to corrupt the Guards, lest they should reveal what had been offer'd them.
