earnestly, "than the fitting of all to each, the search for hidden keys,
the linking of problems that seemed apart? These are the things that
move me. I must walk soberly, Fra Giulio, lest I miss some revelation,
so sacred and so mysterious is knowledge! And the love of it leaves me
no room for questions of outside beauty--this ordered beauty of hidden
law is so wonderful!"

For one moment, as Fra Giulio had looked at him, he fancied that he had
seen deeper into his eyes than ever before; then the veil had seemed to
rise up from the boy's heart and close over its depths. If it had been a
moment of self-revelation the young friar was again protected by that
baffling calm as he glanced about him, turning affectionately to his old
friend. "It pleaseth me that thou art pleased," he said.

Fra Giulio had answered with a sigh. It was hard for one who loved so
truly to get so near, yet be no nearer. "I could wish that thou also
shouldst take pleasure in this beauty, my Paolo, for thou art missing a
joy that God permits."

Then the youthful scholar had turned his eyes upon him silently; and it
had seemed to the old man, in his great love, that a sudden glory had
transfigured the grave young face like a consecration. He still

come to us as we follow its call, are in the measure which He hath
decreed for us."

Now that the convent rang with his triumphs, and Fra Paolo was often
absent from his cell on missions of honor, the old friar sometimes
wondered how many of those philosophic and scientific truths which had
made him famous as an original thinker had come to the lad in
glimmerings on that first night among the hills, when, turning to his
old friend and stretching out his hands with a solemn, imploring motion
which seemed to confess a desperate need of isolation, he had said only,
"Let me think!"

Had his seeming nearness to the stars in the convent _loggia_ brought
him a premonition of the later message which had made him the "friend
and master" of Galileo?

Did he develop his "Laws of Sound" in that voiceful silence; or was it
in that solitude he had first watched the gentle ebb and flow of his own
life-current and learned the secret which Harvey, later, uttered to the
world?

Or had he been wholly absorbed in those philosophical questions which he
so brilliantly disputed at t
