// Mild Splendour of the various-vested Night!
// Mother of wildly-working visions! hail
// I watch thy gliding, while with watery light
// Thy weak eye glimmers through a fleecy veil;
// And when thou lovest thy pale orb to shroud
// Behind the gather’d blackness lost on high;
// And when thou dartest from the wind-rent cloud
// Thy placid lightning o’er the awaken’d sky.
