He was six years old, and the world was to him enormous, alive and bewitchingly mysterious. He knew the sky quite well. He knew its deep azure by day, and the white-breasted, half silvery, half golden clouds slowly floating by. He often watched them as he lay on his back upon the grass or upon the roof. But he did not know the stars so well, for he went to bed early. He knew well and remembered only one star the green, bright and very attentive star that rises in the pale sky just before you go to bed, and that seemed to be the only star so large in the whole sky.
