generation had now been consumed in this controversy, a controversy which touched all lives, and cemented or divided families. The children were reading Luther's Bible, and singing Luther's hymns, and learning Luther's short catechism. Could it be expected that such a river should suddenly lose itself in the sand? Nevertheless there is something surprising in the quick revolution of the story. In 1550 Maurice of Saxony intrigues with the Protestants, and in the following year definitely goes over to their side. In 1552 the emperor has to flee for his life, and the Peace of Passau seals the victory of the Protestant cause. One of the first provinces to be conquered for Lutheranism was the duchy of Pomerania. John Bugenhagen, himself a Pomeranian and the historian of Pomerania, was the chief apostle of this northern region, and those who visit the Baltic churches will often see his sable portrait hanging side by side with Huss and Luther on the whitewashed walls. Sastrow gives us an excellent picture of the various forces which co-operated with the teaching of Bugenhagen to effect the change. In Eastern Pomerania there was the violent propaganda of Dr. Amandus, who wanted a clean sweep of images, princes, and established powers. There was the democratic movement in Stralsund, led by the turbulent Rolof Moller, who, accusing the council of malversation, revolutionized the constitution of his city. There was the mob of workmen who were only too glad of an excuse to plunder the priests and break the altars. But side by side with greed and violence there was the moral revolt against "the fables, the absurdities, and the impious lies" of the pulpit, and against the vices of priest and monk. The recollection of the early days of Puritan enthusiasm, when the fathers of the Protestant movement preached the gospel to large crowds in the open air, as, for instance, under "St. George's churchyard elm" at Stralsund, remained graven on many a lowly calendar. Even the texts of these sermons were remembered as epochs in spiritual life. Sastrow records how, ceding to the request of a great number of burgesses, Mr. Ketelhot (being detained in the port of Stralsund by contrary winds), preached upon Matthew xi. 28: "Come unto Me, all ye that labour and are heavy laden, and I will give you rest"; and then upon John xvi. 23: "Verily, verily, I say unto you, Whatsoever ye shall ask the Father in My name, He will give it you"; and, finally: "Go ye therefore and teach all nations." The general pride in civic monuments proved to be stronger than the iconoclastic mood. Certainly the high altar in the Nicolai Kirche at Stralsund--probably the most elaborate specimen of late fifteenth-century wood carving which still survives in Germany--would have received a short shrift from Cromwell's Ironsides.
