It's possible heroic efforts will be made and some piece of the statue could be preserved for another few millennia. But eventually, whether its in a museum or out in the elements, atom by atom, it will fade. In a way, its already suffered one kind of death. At its creation, it was a statue of a ruler its people viewed as a God. It had a talismanic power. Now it's only relevant because it's an example of ancient sculpture. Hordes of tourists walk by every day, taking a quick glance at a ruler that few remember, slowly falling apart in a dusty old museum.
I met a traveller from an antique land,Who said—“Two vast and trunkless legs of stoneStand in the desert. . . . Near them, on the sand,Half sunk a shattered visage lies, whose frown,And wrinkled lip, and sneer of cold command,Tell that its sculptor well those passions readWhich yet survive, stamped on these lifeless things,The hand that mocked them, and the heart that fed;And on the pedestal, these words appear:My name is Ozymandias, King of Kings;Look on my Works, ye Mighty, and despair!Nothing beside remains. Round the decayOf that colossal Wreck, boundless and bareThe lone and level sands stretch far away.
