But there was no response. The bird stood there, a dumb thing: you see, it could not sing because there was nobody there to wind it up. Then, as Death fastened his empty sockets upon him, a terrible silence fell. Deeper and deeper it grew, and the emperor could hear nothing but the beating of Death's heart—his own would soon be silent.
Suddenly through the open window came a lovely burst of song. Radiant, sparkling as a shower of pearls, the living notes of rarest melody fell within the silent chamber. It was the Nightingale, perched on a branch outside—the Nightingale as God had made it, singing the song that God had taught it. It had heard the emperor's call, and had come to bring him comfort.
Slowly, slowly, as it sang divinely, the faces that peered round the velvet folds grew wan. Pale Death himself started, and turned still paler with wonder and amazement. 'How beautiful!' he said; 'sing on, little bird, thrilling with life!'
'Lay down the imperial banner,' answered the Nightingale; 'lay down the golden sword; lay down the emperor's crown.'
'Agreed!' And the mighty snatcher, Death, laid down these treasures for the price of a song. The Nightingale went on singing. And it sang as it flitted from bough to bough, until it reached the quiet churchyard where the grass grows green upon the graves, where the roses bloom living on the breast of death, and the cypress points to the immortal skies. There on the cypress' topmost twig it perched and sang a song so rich and rare, so far-reaching, that it touched the heart of Death sitting on the chest of the emperor,—for, after all, Death has a tender heart. Filled with a longing for his own garden, melted by the Nightingale's song, he vanished in a cold, grey mist,—out at the window.
Soon came the Nightingale fluttering with delight above the emperor's bed. Then it perched by the side of the toy bird, and the emperor looked, and knew at last the difference between the natural and the artificial. He knew, too, that he ought to have known it before.
'You heavenly little bird!' he said. 'Welcome back to my heart! I banished you from my kingdom, but you heard my call and returned to charm away those evil visions, and even Death himself. Thanks! A world of thanks! How can I ever repay you?' Tears shone in the emperor's eyes.
'I am already repaid,' said the Nightingale. 'When first I sang to you I saw tears in your eyes, and now I see them again. Those are the jewels that I wear in my heart, not upon my coat. But sleep now; you must get well. Sleep—I will sing you to sleep!'
So the little bird sang, and the emperor fell into a healing sleep. In the morning, when the sun shone in at the window, he awoke refreshed and well. Where were his attendants? None was there: they were all busy running after the emperor-elect. But the Nightingale was there, perched on the window-sill, singing divinely.
