Read the analysis of a theme from "Ode on a Grecian Urn."One theme in "Ode on a Grecian Urn" is that art is an eternal and unchanging truth.Now, read the passage from "Ozymandias," another poem from the Romantic period.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.
