"Not at all! Men fail, but man succeeds. I don't know what it all means, or any part of it; but I have had moods in which it seemed as if the whole, secret of the mystery were about to flash upon me. Walking along in the full sun, in the midst of men, or sometimes in the solitude of midnight, poring over a book, and thinking of quite other things, I have felt that I had almost surprised it."

"But never quite?"

"Oh, it isn't too late yet."

"I hope you won't have your revelation before I get away from Florence, or I shall see them burning you here like the great frate."

They had been walking down the Via Calzioli from the Duomo, and now they came out into the Piazza della Signoria, suddenly, as one always seems to do, upon the rise of the old palace and the leap of its tower into the blue air. The history of all Florence is there, with memories of every great time in bronze or marble, but the supreme presence is the martyr who hangs for ever from the gibbet over the quenchless fire in the midst.

"Ah, they had to kill him!" sighed the old man. "It has always been so with the benefactors. They have always meant mankind more good than any one generation can bear, and it must turn upon them and destroy them."

"How will it be with you, then, when you have read us 'the riddle of the painful earth'?"

"That will be so simple that every one will accept it willingly and gladly, and wonder that no one happened to think of it before. And, perhaps, the world is now grown old enough and docile enough to receive the truth without resentment."

"I take back my charge of pessimism," said Colville. "You are an optimist of the deepest dye."

They walked out of the Piazza and down to the Lung' Arno, through the corridor of the Uffizzi, where the illustrious Florentines stand in marble under the arches, all reconciled and peaceful and equal at last. Colville shivered a little as he passed between the silent ranks of the statues.
