As great, or a greater, danger embarrassed Cromwell from the folly of his friends. So long as the tide was in their favour, the Protestants indulged in insolent excesses, which provoked, and almost justified the anger with which they were regarded. Hitherto they had held a monopoly of popular preaching. Tradition and authority had been with the Catholics: the rhetoric had been mainly with their adversaries. In the summer the interest of London was suddenly excited on the other side by a Catholic orator of extraordinary powers, a Dr. Watts, unknown before or after this particular crisis, but for the moment a principal figure on the stage. Watts attracted vast audiences; and the Protestants could not endure a rival, and were as little able as their opponents to content themselves with refuting him by argument. He was summoned, on a charge of false doctrine, before the Archbishop of Canterbury; and even moderate persons were scandalized when they saw Barnes sitting by the side of Cranmer as assessor in a cause of heresy.[530] It appeared, and perhaps it was designed, as an insult--as a deliberately calculated outrage. Ten thousand London citizens proposed to walk in procession to Lambeth, to require the restoration of their teacher; and, although the open demonstration was prevented by the City officers, an alderman took charge of their petition, and offered, unless the preacher's offence was high treason, to put in bail for him in the name of the corporation.[531] [Sidenote: Sept 17. In whose behalf the corporation interfere in vain.] There were, perhaps, circumstances in the case beyond those which appear; but, instead of listening to the request of the City, the archbishop spirited away the preacher into Kent, and his friends learned, from the boasts of their adversaries, that he was imprisoned and ill used. He was attached, it seems, to the Victuallers' Company. "There is no persecution," wrote a Protestant fanatic, "except of the Victuallers; of which sect a certain impostor of the name of Watts, formerly of the order of wry-necked cattle, is now holding forth, oh, shame! in the stocks at Canterbury Bridewell, having been accustomed to mouth elsewhere against the Gospel."[532] [Sidenote: Charles V. endeavours to prevent the German marriage.]
