Succeeding years witnessed similar astonishing pilgrimages—in 1489, to the “black Mother of God” in Altötting; in 1492, to the “Holy Blood” at Sternberg; in the same year, to the “pitiful Bone” at Dornach; in 1499, to the picture of the Blessed Virgin at Grimmenthal; in 1500, to the head of St. Anna at Düren; and in 1519, to the “Beautiful Mary” at Regensburg. Apart altogether from these sporadic movements, the last decades of the fifteenth century were pre-eminently a time of pilgrimages. German princes and wealthy merchants made pilgrimages to the Holy Land, visited the sacred places there, and returned with numerous relics, which they stored in favourite churches. Frederick the Wise, the Elector of Saxony, to be known afterwards as the protector of Luther, made such a pilgrimage, and placed the relics he had acquired in the Castle Church (the Church of All Saints) in Wittenberg. He became an assiduous collector of relics, and had commissioners on the Rhine, in the Netherlands, and at Venice, with orders to procure him any sacred novelties they met with for sale.(80) He procured from the Pope an Indulgence for all who visited the collection and took part in the services of the church on All Saints’ Day; for it is one of the ironies of history that the church on whose door Luther nailed his theses against Indulgences was one of the sacred edifices on which an Indulgence had been bestowed, and that the day selected by Luther was the yearly anniversary, which drew crowds to benefit by it.(81) A pilgrimage to the Holy Land was too costly and dangerous to be indulged in by many. The richer Germans made pilgrimages to Rome, and the great pilgrimage place for the middle-class or poorer Germans was Compostella in Spain. Einsiedeln, in Switzerland, also attracted yearly swarms of pilgrims.
