In 1677 George Fox, William Penn, Robert Barclay, and some other Friends, went over to Holland on a religious visit, and travelled into Germany. In the course of this journey, William Penn and two other Friends visited Elizabeth, Princess Palatine of the Rhine, at her Court at Herwerden. She was the oldest daughter of Frederick V., Elector Palatine, and at one time King of Bohemia; her mother being the sister of Charles I. of England. She is represented to have been a woman of good natural capacity, well educated, and of amiable disposition and manners; and to have governed her small territory with good judgment and much consideration for the welfare of her subjects. Having been brought under the power of religion, she manifested strong interest in others who were sincere in their religious convictions, and was opposed to interference with liberty of conscience. Having become acquainted with the religious tenets of Friends, by conversation with Robert Barclay and Benjamin Furly, who visited her in 1676, and with women Friends from Amsterdam, she found them to answer to the convictions of Truth on her own mind; and she not only gladly received Friends when they came to see her, but in her letters to several of the more prominent members among them, and to others at the English Court, she unhesitatingly expressed her high estimation of them, and her disapproval of the persecution to which those that held them were subjected. The Friends named, having requested permission to have a religious opportunity with her, it was readily granted; she having in her family at that time the Countess of Hornes, her intimate friend, and a French lady. Of this interview William Penn thus writes in his journal: "I can truly say it, and that in God's fear, I was very deeply and reverently affected with the sense that was upon my spirit of the great and notable day of the Lord, and the breaking in of his eternal power upon all nations; and of the raising of the slain Witness to judge the world; who is the Treasury of life and peace, of wisdom and glory, to all that receive Him in the hour of his judgments, and abide with Him. The sense of this deep and sure foundation, which God is laying as the hope of eternal life and glory for all to build upon, filled my soul with an holy testimony to them, which in a living sense was followed by my brethren; and so the meeting ended about the eleventh hour." In the afternoon they held another meeting with them, which was also so remarkably favored, that William Penn says: "Well, let my right hand forget its cunning, and my tongue cleave to the roof of my mouth, when I shall forget the loving-kindness of the Lord, and the sure mercies of our God to us, his travailing servants, that day."
