The Romantic writers thrived predominately between 1800-1837. Three of the movement's most well-known writers—Byron, Shelley and Keats—all died tragically before they were forty. However, the amount of writing produced by these men is amazing, as is the wealth and quality of writing from the earliest Romantic writers: William Wordsworth and Samuel Taylor Coleridge.
There is a great deal of controversy regarding the characteristics of Romantic writing. A few examples include the "idealization of women and children," "champions of personal freedom," and especially a return to valuing nature. (For instance, in the famous epic poem by Samuel Taylor Coleridge called The Rime of the Ancient Mariner, many of the characteristics of Romantic writing are included.) The story deals with a mariner's (sailor's) wanton destruction of a sea bird and the punishment visited upon all the members of the sea vessel on which he travels—punishment which only stops when the mariner learns to deeply appreciate nature and realize what a horrible thing he did in destroying a beautiful piece of nature.
In "Lines Composed a Few Miles Above Tintern Abbey," Wordsworth spends a great deal of time describing the beauty of nature, and speaking even of its power over him when he is away from this place he so loves, and how much better he feels just thinking about it.
We learn at the beginning that it has been five years since Wordsworth visited the area, but he has had it in his mind on many occasions during that time. To make his imagery effective, Wordsworth uses literary devices. For example, as the poem begins, the author describes the water that he hears:
...and again I hear
These waters, rolling from their mountain-springs
With a sweet inland murmur.
"Murmur" is a human characteristic, so the device used is personification, allowing us to imagine the gentle rumbling of the water as it moves, almost like the murmuring of a voice.
Another aspect of Romanticism is that of the supernatural or the occult. In Wordsworth's descriptions, the ability of nature to "speak" to him across the years and miles takes on a magical element. He even speaks to the effects of nature on the body and the soul:
…And even the motion of our human blood
Almost suspended, we are laid asleep
In body, and become a living soul...
In this case, it is only the communion with nature—putting away the activities and distractions of the world—when one's soul truly comes alive. A reference to, or interest in, the past (another of the Romantic elements) speaks of days when he was a young man...
...my boyish days,
And their glad animal movements...
...I cannot paint
What then I was.
Melancholy is also an aspect of Romantic writing. Here Wordsworth speaks about how sadness sometimes comes to him when he thinks of the "music of humanity."
The still, sad music of humanity,
Not harsh nor grating, though of ample power
To chasten and subdue.
There are a number of Romantic characteristics in the poem, and they are all tied to having an appreciation for nature.
