"A little dreaming would not hurt thee, my Paolo; for sometimes it seemeth to those who care for thee that thou needest rest."

"Rest is satisfaction," the lad answered quickly. "If there be a problem to be solved, I would rather think than dream. I would rather come in contact with the nobler activities—the mental and spiritual forces—through the minds and works of men. I would find such attrition more helpful than this phase of creation which thou callest 'nature,' whose unfolding is more passive, depending on its inherent law."

"This also is of God's gift, Paolo mio," Fra Giulio had said yearningly.
"Sometimes thou seemest to find too little beauty in thy life, and when
I brought thee hither I hoped it might move thy soul."

"What can be more beautiful," the young philosopher had questioned 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 remembered the tones of that clear voice saying serenely: "My Father, when God speaketh a message in our souls, the peace and beauty which 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?
