Campion was afterwards detected in treasonable practices; and being put to the rack, and confessing his guilt, he was publicly executed.

His execution was ordered at the very time when the duke of Anjou was in England, and prosecuted, with the greatest appearance of success, his marriage with the queen; and this severity was probably intended to appease her Protestant subjects, and to satisfy them, that whatever measures she might pursue, she never would depart from the principles of the reformation.
The duke of Alencon, now created duke of Anjou, had never entirely dropped his pretensions to Elizabeth; and that princess, though her suitor was near twenty-five years younger than herself, and had no knowledge of her person but by pictures or descriptions, was still pleased with the image, which his addresses afforded her, of love and tenderness.

The duke, in order to forward his suit, besides employing his brother's ambassador, sent over Simier, an agent of his own; an artful man, of an agreeable conversation, who soon remarking the queen's humor, amused her with gay discourse, and instead of serious political reasonings, which he found only awakened her ambition, and hurt his master's interests, he introduced every moment all the topics of passion and of gallantry.

The pleasure which she found in this man's company soon produced a familiarity between them; and amidst the greatest hurry of business, her most confidential ministers had not such ready access to her as had Simier, who, on pretence of negotiation, entertained her with accounts of the tender attachment borne her by the duke of Anjou.
The earl of Leicester, who had never before been alarmed with any courtship paid her, and who always trusted that her love of dominion would prevail over her inclination to marriage, began to apprehend that she was at last caught in her own snare, and that the artful encouragement which she had given to this young suitor had unawares engaged her affections.

To render Simier odious, he availed himself of the credulity of the times, and spread reports, that that minister had gained an ascendant over the Queen, not by any natural principles of her constitution, but by incantations and love potions.
