[MC] Rоderick Usher's pоemBy Edgаr Allаn Pоe In the greenest of our vаlleys, By good angels tenanted,Once a fair and stately palace— Radiant palace—reared its head.In the monarch Thought's dominion— It stood there!Never seraph spread a pinion Over fabric half so fair. Banners yellow, glorious, golden, On its roof did float and flow;(This—all this—was in the olden Time long ago);And every gentle air that dallied, In that sweet day,Along the ramparts plumed and pallid,A winged odor went away. Wanderers in that happy valley Through two luminous windows sawFigures moving musically To a lute's well-tun´d law;Round about a throne, where sitting (Porphyrogene!)In state his glory well befitting, The ruler of the realm was seen.
