"Some of us awake in the night with strange phantasms of enchanted hills and gardens, of fountains that sing in the sun, of golden cliffs overhanging murmuring seas, of plains that stretch down to sleeping cities of bronze andstone, and of shadowy companies of heroes that ride caparisoned white horsesalong the edges of thick forests, and then we know that we have looked backthrough the ivory gates into that world of wonder that was ours, before we were wise and unhappy."
