3. His Prose. Shelley began his literary career with two boyish romances, Zastrozzi and St. Irvyne. These books were written when he was still at school, and are almost laughably bad in style and story. The only other prose work that is worth mention is his short essay The Defence of Poetry. The work is soundly written, and is a strong exposition of the Romantic point of view. His published letters show him to have been a man of considerable common sense, and not merely the crazy theorist of popular imagination. His prose style is somewhat heavy, but always clear and readable.
4. Features of his Poetry. (a) His lyrical power is equal to the highest to be found in any language. It is now recognized to be one of the supreme gifts in literature, like the dramatic genius of Shakespeare. This gift is shown at its best when it expresses the highest emotional ecstasy, as in the lyrics of Prometheus Unbound. It is a sign of his great genius that, in spite of the passion that pervades his lyrics, he is seldom shrill and tuneless. He can also express a mood of blessed cheerfulness, a sane and delectable joy. To the Spirit of Delight he says:
I love Love, though he has wings,
And like light can flee,
But above all other things,
Spirit, I love thee.
Thou art love and life! O come,
Make once more my heart thy home.
He can also express the keenest note of depression and despair, as in the lyric O World! O Life! O Time!
(b) In his choice of subject he differs from such a poet as Burns, who is almost the only other poet who challenges him as master of the lyric. Shelley lacks the homely appeal of Burns; he loves to roam through space and infinity. In his own words he
