To a Lady, XLIX

But God forbid that I should dare Discover, what I next saw there: Or tell the music, or the word, That from immortal tongues I heard. I saw, but oh I must not tell, The vision was unspeakable! Millions on millions, bright to see, All crowding through Immensity: Myriads on myriads, far away, To keep the worship of that day, That stood in serried, close array, And bent, and sway’d them, to the breeze Of soul-controlling harmonies; As if the heavenly fields were sown With wavy light, to harvest grown.
