So flagrant are, however, the sins of love at that brilliant court which did so much for classical, Germanic, and sacred learning in Germany, that even the saga, in dim recollection of past events, seized upon Charlemagne's towering figure in respect to his moral side. He is represented by a later legend as having been misled into grievous sins by a mysterious, magic precious stone in a ring which he had presented to his queen. As long as she wore the ring, he could not live away from her. At last the queen fell ill and came to die. But grudging the stone to any other woman and desiring that the king might not love another as he loved her, she concealed the ring under her tongue and died. Charlemagne unable to live without her did not allow her to be buried, but carried her with him day and night on the journey through his vast realm. An inexpressible sin, due to the magic ring in her mouth, ensued. At last, when Charlemagne was absent, the corpse of the dead woman was examined and the ring was found in her mouth. A knight took the ring away and kept it. Charlemagne had the queen buried at once. But all the love which he bore to his dead wife, he now transferred to the knight as long as the latter possessed the stone. The knight, annoyed by this love and the shame thereof, threw away the stone into a morass. Charlemagne conceived such an affection for the place where the ring lay that he built there the Cathedral of Our Lady at Aachen (Aix-la-Chapelle). And, as a higher irresistible power had brought about the moral sins as well as other sins bearing the character of incest, Saint Ægidius and Saint Theodolin secured for him atonement, expiation, and absolution.
