"Gently, brothers," murmured the greatest physician of his age in a low voice, as, leaning on a staff, he went toward the row of couches. It was easy to see the traces of his eighty years, but his fine eyes still gleamed with youthful light.

Melissa blushed to think that she could have mistaken Serenus Samonicus for this noble old man. He must once have been a tall man; his back was bent and his large head was bowed as though he were forever seeking something. His face was pale and colorless, with a well-formed nose and mouth, but not of classic mold. Blue veins showed through the clear white skin, and the long, silky, silvery hair still flowed in unthinned waves round his massive head, bald only on the crown. A snowy beard fell over his breast. His aged form was wrapped in a long and ample robe of costly white woolen stuff, and his whole appearance would have been striking for its peculiar refinement, even if the eyes had not sparkled with such vivid and piercing keenness from under the thick brows, and if the high, smooth, slightly prominent forehead had not borne witness to the power and profundity of his mind. Melissa knew of no one with whom to compare him; he reminded Andreas of the picture of John as an old man, which a wealthy fellow-Christian had presented to the church of Saint Mark.

If this man could do nothing, there was no help on earth. And how dignified and self-possessed were the movements of this bent old man as he leaned on his staff! He, a stranger here, seemed to be showing the others the way, a guide in his own realm. Melissa had heard that the strong scent of the kyphi might prove injurious to Diodoros, and her one thought now was the desire that Galenus might soon approach his couch. He did not, in fact, begin with the sick nearest to the door, but stood awhile in the middle of the hall, leaning against a column and surveying the place and the beds.

When his searching glance rested on that where Diodoros was lying, an answering look met his with reverent entreaty from a pair of beautiful, large, innocent eyes. A smile parted his bearded lips, and going up to the girl he said: "Where beauty bids, even age must obey. Your lover, child, or your brother?"

"My betrothed," Melissa hastened to reply; and the maidenly embarrassment which flushed her cheek became her so well that he added:

"He must have much to recommend him if I allow him to carry you off, fair maid."

With these words he went up to the couch, and looking at Diodoros as he lay, he murmured, as if speaking to himself and without paying any heed to the younger men who crowded round him:

"There are no true Greeks left here; but the beauty of the ancestral race is not easily stamped out, and is still to be seen in their descendants. What a head, what features, and what hair!"

Then he felt the lad's breast, shoulders, and arms, exclaiming in honest admiration, "What a godlike form!"

He laid his delicate old hand, with its network of blue veins, on the sick man's forehead, again glanced round the room, and listened to Ptolemaeus, who gave him a brief and technical report of the case; then, sniffing the heavy scent that filled the hall, he said, as the Christian leech ceased speaking:
