But their horses were quick, and their driver did not stop for a long view; and after a turn or two they were soon crossing the sunny, paved piazza in front of St. Peter's, with its obelisk and fountain.

"This is to be only the most general view. You must come again some day when there is a great ceremony, when you can see various dignitaries; now you are merely to get a first impression."

"A first impression!" cried Irma. "Can I put it into words? It's a tremendous building; I shall never see another as large, and yet, it doesn't seem too large. What a great man the architect was!"

"I have been reading up a little to-day," said Marion, "so things are fresh in my mind. I won't pretend I'll remember them to-morrow, but it's true that this is not the first church on the spot. In the beginning there was a circus of Nero's here, where that beautiful emperor was in the habit of torturing Christians to death. There's a tradition that St. Peter himself was burned here, and so Constantine built the first St. Peter's over the spot. Perhaps we can go down into the tomb to-day."

"But this isn't Constantine's church?" There was a decided note of interrogation in Irma's voice. Perhaps it would have been better for her not to ask the question, for Marion's reply was in the nature of a snub.

"Any one can see that this St. Peter's is comparatively new. It was begun by Julius II in the first part of the sixteenth century, and Bramante probably made the original plans."

"Why, I thought Michelangelo——"

"Yes, my dear," interposed Uncle Jim, "in the end Michelangelo did come to the rescue of the first plan. For after Bramante died, leaving the building far from completed, some of his successors made changes that affected the beauty of the building. I believe the dome was largely the result of Michelangelo's skill."
