ruin

"In the ruin history has physically merged into the setting. And in this guise history does not assume the form the process of an eternal life so much as that of irresistable decay. Allegory thereby declares itself to be beyond beauty. Allegories are, in the realm of thoughts, what ruins are in the realm of things. " (Walter Benjamin, Origins, pp 178-9)
