She knew that he was not yet thirty, but yesterday, as he drove past her, he had looked like a surly misanthropist of more than middle age.  To-day how young he seemed!  Did he owe it to the laurel crown which rested on his head, or to the white toga which fell about him in ample folds, leaving only the sinewy arm bare by which he led the lion?

From where she stood she could only see his side-face as he came down the steps, and indeed it was not ill-favored; brow, nose, and chin were finely and nobly formed; his beard was thin, and a mustache curled over his lips.  His eyes, deeply set under the brows, were not visible to her, but she had not forgotten since yesterday their sinister and terrible scowl.

At this moment the lion crept closer to his master.

If only the brute should spring on that more blood-stained and terrible beast of prey who could kill not only with claws and teeth but with a word from his lips, a wave of his hand!—­the world would be rid of the ferocious curse.  Ay, his eye, which had yesterday scorned to look at the multitudes who had hailed his advent, was that of a cruel tyrant.

And then—­she felt as if he must have guessed her thoughts—­while he patted the lion and gently pushed him aside he turned his face full on her, and she knew not whether to be pleased or angry, for the odious, squinting eyes were not now terrible or contemptuous; nay, they had looked kindly on the beast, and with a somewhat suffering expression.  The dreadful face of the murderer was not hideous now, but engaging—­the face of a youth enduring torments of soul or of body.

She was not mistaken.  On the very next step Caracalla stood still, pressed his right hand to his temples, and set his lips as if to control some acute pain.  Then he sadly shook his head and gazed up at the walls of the court, which had been decorated in his honor with hangings and garlands of flowers.  First he studied the frieze and the festal display on his right, and when he turned his head to look at the side where Melissa stood, an inward voice bade her withdraw, that the gaze of this monster might not blight her.  But an irresistible attraction held her fast; then suddenly she felt as if the ground were sinking from under her feet, and, as a shipwrecked wretch snatches at a floating spar, she clung to the little column at the left of the window, clutching it with her hand; for the dreadful thing had happened-Caracalla’s eye had met hers and had even rested on her for a while!  And that gaze had nothing bloodthirsty in it, nor the vile leer which had sparkled in the eyes of the drunken rioters she had met last night in the streets; he only looked astonished as at some wonderful thing which he had not expected to see in this place.  But presently a fresh attack of pain apparently made him turn away, for his features betrayed acute suffering, as he slowly set his foot on the next step below.

Again, and more closely, he pressed his hand to his brow, and then beckoned to a tall, well-built man with flowing hair, who walked behind him, and accepted the support of his offered arm.
