"The nostalgia of things unknown, of lands forgotten or unfound, is upon me at times. Often I long for the gleam of yellow suns upon terraces of translucent azure marble, mocking the windless waters of lakes unfathomably calm; for lost, legendary palaces of serpentine, silver and ebony, whose columns are green stalactites; for the pillars of fallen temples, standing in the vast purpureal sunset of a land of lost and marvellous romance. I sigh for the dark-green depths of cedar forests, through whose fantastically woven boughs, one sees at intervals an unknown tropic ocean, like gleams of blue diamond; for isles of palm and coral, that fret an amber morning, somewhere beyond Cathay or Taprobane; for the strange and hidden cities of the desert, with burning brazen domes and slender pinnacles of gold and copper, that pierce a heaven of heated lazuli."
"Nostalgia of the Unknown" - Clark Ashton Smith
