As Admetus bowed his head the stranger loosed the curious instrument from his girdle. The body of it was the hollow shell of a tortoise, in the rim of which two twisted horns were cunningly fitted, joined together towards the top by a silver band. The space between the band and the furthermost edge of the shell was spanned by seven strings of gold. Lovingly he drew his fingers across the strings, and the chords rang soft and true through the silence of the hall, as he played a prelude to his song, and anon raised his voice and sang. He sang a strange, sweet song, such as no man there had ever heard, and yet in the depths of his soul each one of them felt that he had known it before he was born. For the song that the stranger sang was the song that the stars first sang together when the universe was born, and light sprang forth from the darkness. The melody they made that day vibrates for ever till the end of time. Musicians and artists and poets, and those whom the gods love, hear it and sing it, each in his separate way, for those who have forgotten the sound of it. Deep in the heart of every man it lies voiceless, till once at least in his lifetime the hand of the divine musician sets the chords vibrating, and opens the ears of the soul to hear the heavenly harmonies. Such was the song that the stranger sang, and the people sat breathless beneath his spell, and gazing deep into the red-hot heart of the fire, saw strange dreams and visions. The very dogs awoke from their sleep, and crept closer to the music, and with their heads between their paws, gazed with unblinking eyes at the singer; and a magic thrill ran round the circle of them that listened, both man and beast, and welded and fused their souls in one, so that they felt that the life in them all was the same. When the song was ended, silence fell upon all things--even the storm outside had ceased to rage; and Time stood still as each man sat motionless in his seat, with heart too full for speech. But at length the spell was broken, and with a sigh and a whisper, they glided away to their rest, till Admetus and the stranger were left face to face before the hearth. "O divine musician," said Admetus, "I know not who thou art. This only do I know, that I could worship thee for the godlike beauty of thy song, and follow thee and serve thee all my days." "Nay, O king; 'tis destined that I must serve thee, and be thy servant for a year. To-morrow I will lay aside this silken doublet, and put on the dress that suits my station, and go forth with the other shepherds of thy flocks." "O stranger, this thing can never be. Who am I that thou shouldst be my servant?"
