But the moment the curtain went up, she became the mediæval German princess; her other life fell behind her, and her father was but a little shadow on her brain. Yet he was the inspiration of her acting, and that night the whole theatre consisted for Evelyn of one stage-box. Her eyes never wandered there, but she knew that there sat her ultimate judge, one whom no excess or trick could deceive. He would not judge her by the mere superficial appearance she presented on the stage, by the superficial qualities of her voice or her acting; he would see to the origin of the idea, whence it had sprung, and how it had been developed. He did not know this particular opera, but he knew all music, and would judge it and her not according to the capricious taste of the moment, but in its relation and her relation to the immutable canons of art, from the plain chant to Palestrina, from Palestrina to Bach and Beethoven. Her singing of every phrase would be passed as it were through the long tradition of the centuries; it would not be accepted as an isolated fact, it would be judged good, indifferent or bad, by learned technical comparison. That she was his daughter would weigh not a hair's weight in the scale, and the knowledge of this terrible justice raised her out of herself, detached her more completely from the superficial and the vulgar. She sang and acted as in a dream, hypnotised by her audience, her exaltation steeped in somnambulism and steeped in ecstasy. The curtain was raised several times, but that night the only applause or censure she was minded to hear awaited her in her dressing-room. She sent her maid out of the room, and waited for some sound of footsteps in the corridor, and at the first sound she rushed to the door and flung it open. It was her father, Merat was bringing him along the corridor, and they stood looking at each other; her clear, nervous eyes were trembling with emotion. His face seemed to tell her that he was pleased; she read upon it the calm exaltation of art, yet she could not however summon sufficient courage to ask him, and they sat down side by side. At last she said-- "Why don't you speak? Aren't you satisfied? Was I so bad?" "You are a great artist, Evelyn. I wish your mother were here to hear you." "Is that really true? Say it again, father. You are satisfied with me. Then I have succeeded." He told her why she had sung well, and he knew so well. It was like walking with a man with a lantern; when he raised the light, she could see a little farther into the darkness. But she had still the prayer to sing to him. She wanted to know what he would think of her singing of the prayer. The voice of the call-boy interrupted them. She sang the prayer more purely than ever, and the flutes and clarionettes led her up a shining road, and when she walked up the stage she seemed to disappear amid the palpitation of the stars.
