Our windows at the hotel looked out on the finest front of the cathedral. If the Devil really built it, he is to be credited with one good thing, and it is now likely to be finished, in spite of him. Large as it is, it is on the exterior not so impressive as that at Amiens; but within it has a magnificence born of a vast design and the most harmonious proportions, and the grand effect is not broken by any subdivision but that of the choir. Behind the altar and in front of the chapel, where lie the remains of the Wise Men of the East who came to worship the Child, or, as thev are called, the Three Kings of Cologne, we walked over a stone in the pavement under which is the heart of Mary de Medicis: the remainder of her body is in St. Denis near Paris. The beadle in red clothes, who stalks about the cathedral like a converted flamingo, offered to open for us the chapel; but we declined a sight of the very bones of the Wise Men. It was difficult enough to believe they were there, without seeing them. One ought not to subject his faith to too great a strain at first in Europe. The bones of the Three Kings, by the way, made the fortune of the cathedral. They were the greatest religious card of the Middle Ages, and their fortunate possession brought a flood of wealth to this old Domkirche. The old feudal lords would swear by the Almighty Father, or the Son, or Holy Ghost, or by everything sacred on earth, and break their oaths as they would break a wisp of straw: but if you could get one of them to swear by the Three Kings of Cologne, he was fast; for that oath he dare not disregard.
