"Guidebook information would probably be as useful as that of a misguided guide," said Irma, refusing to express herself about the Stuarts.
"Twenty-nine altars and one hundred and forty-eight columns," read Marion.
"Come," said Uncle Jim, "don't listen to him. I can show you something better worth seeing," and he led her to the nave, where he showed her in the pavement the round slab of porphyry on which the emperors were formerly crowned.
"Why, Charlemagne, of course," began Irma, and then she reddened. For Marion was standing near, and she suddenly realized that Charlemagne had been dead eight hundred years before St. Peter's was consecrated.
"Oh, it was in Constantine's church that Charlemagne was crowned, but though this slab is older than the present St. Peter's, I doubt that he or his earlier successors stood on it, and best of all, I doubt that Marion can inform us," he concluded in a whisper.
When at last the four turned toward the door, Irma noticed the people about her more than she had on entering. Bareheaded peasants were walking about in groups; laboring men, who had stolen an hour from work, bowed before various altars. Tourists of all nations were studying mosaic pictures, sculptured tombs, or were gazing at the priests in rich vestments and the altar boys in one of the chapels where there was a service. Here an old woman hobbled along, and there was a mother with two or three awestruck children. There were two or three soldiers in uniform, and several long-coated priests, visitors evidently from outside Rome.
"It is the People's Church," said Aunt Caroline, "the church of the people of the whole world," she added. "There may not be as many languages as there are people in this large building, but I'll warrant a dozen nations are represented here."
The fifteenth century bronze doors of St. Peter's amused Irma, with their curious mingling of Christian and pagan subjects, Europa and the bull, Ganymede, as well as scenes directly from the scriptures. She had a chance to admire her favorite Charlemagne, whose statue on horseback and one of Constantine were on either side of the entrance.
"Over there," and Uncle Jim pointed to the left, "is the German cemetery, which Constantine originally filled with earth from Mt. Calvary, and made the first Christian burying ground. We have as little time for that to-day as for the sacristy with its treasures, or the chapels with their pictures and sculptures. There is just one other important thing to see before we reach our hotel. Wake up, _cocchiere_, here we are."
