The characteristic features of poetry during the Romantic movement included a celebration of the natural world, a critical attitude towards organized religion, and a celebration of childhood.
William Wordsworth's "Lines composed a Few Miles above Tintern Abbey" is a good example of a Romantic poem which celebrates the natural world. In this poem, the speaker is resting beneath a "dark sycamore" tree and looks admiringly upon "groves and copses" and "little lines / Of sportive wood run wild." He comments on the pleasing "deep seclusion" of the setting and is especially appreciative of the quiet and calm of the countryside because he has become accustomed to the oppressive "din / Of towns and cities."
Romantic poets like Wordsworth celebrated nature in part because the countryside offered a refuge from the burgeoning, industrializing cities. Romantic poets like Wordsworth also celebrated the beauty and wonder of the natural world because they believed that God existed not in sanctified buildings like churches and chapels, but in the trees, lakes, fields, and flowers of nature.
In William Blake's "Garden of Love," we can see how and why Romantic poets were critical of organized, orthodox religion. In this poem, the speaker returns to "the green" that he used to play on as a child, only to find that a "Chapel" has since been built "in the midst" of this green. The speaker notices that "the gates of this Chapel were shut," and that where there had once been "so many sweet flowers," there were now only "graves, / And tomb-stones." The point here is that the natural beauty created by God has been replaced with and destroyed by a "Chapel," representing organized religion.
Romantic poetry also typically celebrates childhood. In Wordsworth's "Ode on Imitations of Immortality from Early Childhood," for example, childhood is celebrated as a time of innocence and purity. The child, in Romantic poetry, is pure and innocent because he or she has been newly created by God and has not yet been spoiled by the world of men. Indeed, Wordsworth writes that the child comes from God "trailing clouds of glory."
