Could you help me find elements of Romanticism in "Tintern Abbey" and "The Tables Turned" by Wordsworth?

Here are a couple of examples to get you started.

Romantic elements in "Tintern Abbey":

In the first stanza, Wordsworth describes an idyllic natural setting and finds comfort and serenity there.  He writes,

"The day is come when I again repose / Here, under this dark sycamore, and view / These plots of cottage-ground, these orchard-tufts . . ." (9-11).

Romantic authors use precise detail when describing nature and associate countryside or natural landscapes with happiness, purity, and peace.

In the second stanza, Wordsworth describes the city and his lonely room in a negative light.  Romantic authors believed that the city was a place of moral depravity and corruption; so notice the difference in the poet's wording about the city versus his worshipful attitude toward the natural setting.

Finally, Wordsworth seeks to find moral enlightment in nature and uses words with religious connotations to describe elements of nature--"holier love," "Worshipper of nature," "guardian of my heart," "anchor of my purest thoughts."

See if you can use these same concepts--a longing to escape from the city, a worshipful attitude toward nature, close attention to the details of natural settings, and moral lesson from nature--to analyze "The Tables Turned."

One more note, structurally, Romantic poems follow a strict format.  They usually have a rhyme scheme, a standard meter, and similar if not identical stanza formation.  You can use the structure of Wordsworth poetry as a Romantic element in addition to his themes and morals.
