St Giles’s church, for the celebration of the Roman catholic worship, were already prepared.[169] But these measures, when ripe for execution, were blasted, in consequence of a secret engagement which the king had entered into with some of the protestant nobles. The first effect produced by this engagement was the well‑known assassination of Rizzio, the unworthy favourite of the queen, who was the principal instigator of the measures against the protestant religion and the banished lords, and had now incurred the jealousy of the king, as well as the contempt of the nobility and the hatred of the people. To have removed this minion from her majesty’s counsels and presence by legitimate means would have been meritorious; but the manner in which it was accomplished was equally inconsistent with law and humanity, and fixes a deep stigma on the characters of those who perpetrated the deed.[170] {145} A complete change on the state of the court succeeded this event. The popish counsellors fled from the palace; the exiled lords returned out of England; and the parliament was prorogued, without accomplishing any of the objects for which it had been assembled. But Mary soon persuaded the weak and uxorious king to desert the noblemen whom he had made the instruments of his revenge, to retire with her to Dunbar, and to issue a proclamation, disowning his consent to the late attempt; by which he exposed himself to the contempt of the nation, without regaining her affection. Having collected an army, she returned to Edinburgh, threatening to inflict the most exemplary vengeance on all who had been accessory to the murder of her secretary, and the indignity shown to her person. She found herself, however, unable to resume her former plans; and, while the conspirators against Rizzio were forced to flee to England, the earl of Murray, and the other lords who {146} had opposed her marriage, were allowed to remain in the country, and soon after pardoned. When the queen returned to Edinburgh, Knox left it, and retired to Kyle. There is no reason to think that he was privy to the conspiracy which proved fatal to Rizzio. But it is probable that he had expressed his satisfaction at an event which contributed to the safety of religion and the commonwealth, if not also his approbation of the object of the conspiracy.[171] At any rate, he was sufficiently obnoxious to the queen on other grounds; and as her resentment, on the present occasion, was exceedingly inflamed, it was deemed prudent for him to withdraw.[172]
