Events in the history of one nation frequently bear a striking similarity to events in that of another. But along with the points of similarity, there are usually in such cases points of contrast also, which make the comparison more interesting than if the similarity had been complete. The life of Thomas à Becket, first the friend and chancellor, then Archbishop of Canterbury and the unyielding opponent of our Henry II., and his violent death before the altar of his cathedral, form one of the most remarkable episodes both in English history and in the history of the long struggle between the so-called temporal and spiritual powers, which is still continuing at the present day. Very singular, also and interesting are both the points of similarity and the points of contrast presented by the life of John of Jenstein, Archbishop of Prague, towards the end of the fourteenth century, and his struggle with Wenceslas IV., King of Bohemia and King of the Romans, as compared with the life of Becket, and his contest with Henry II. of England.
