Regret is often expressed that—with the single exception of “Al Aaraaf,” which, however, was written when his intellect was still in its adolescent stage, and has done comparatively little to enhance his reputation—Poe, almost alone among the great poets of the nineteenth century, should never have given us a poem of any considerable length. But as a journalistic hack, forced to write by the column for his daily bread, Poe had but scant leisure for the composition of a “Childe Harold,” an “Endymion,” or a “Hiawatha,” and, moreover, it is extremely doubtful whether, even if the range of his possibilities had not been limited by his poverty, he would have done so, as he seems to have had a most profound contempt for prolixity in poetry. In his essay, “The Poetic Principle,” he maintains that “the phrase ‘a long poem’ is simply a flat contradiction in terms,”—that a poem deserves its title only inasmuch as it excites by elevating the soul; and that, as all such emotions are, by a psychical necessity, transient, it is obviously impossible for the necessary degree of excitement to be maintained throughout a composition of any great length. “After the lapse of half an hour at the very utmost,” he says, “it flags—fails—a revulsion ensues—and then the poem is, in effect and in fact, no longer such.” This theory of Poe’s gave rise to much hostile criticism, and justly so; still, it cannot be doubted that the time-honoured notion that no poem can be termed great that is not a long one, and no poet worthy of the name who has not written a long poem, has deprived the world of much fine lyric poetry by compelling able men to expend their time and energy in the production of bulky epics, for which in many cases their genius was but ill-adapted, instead of confining themselves to the lighter forms of verse. While thus condemning prolixity, however, Poe does not deny that a poem may be “improperly brief,” and thus “degenerate into mere epigrammatism”; and that “a _very_ short poem,” however great its intrinsic merits may be, can never hope to produce a profound or a lasting effect. He mentions Shelley’s exquisite “Lines to an Indian Air,” and his own friend Willis’s pathetic ballad, “Unseen Spirits,” as instances of poems which had failed to receive adequate recognition by reason of undue brevity. The secret of Poe’s hostility to the long poem is probably to be found in the fact that he had the strongest possible aversion to the introduction of metaphysics into poetry, which he regarded as the “child of Taste,” whose sole function ought to be “the rhythmical creation of Beauty”; and the long poem had to a very large extent become identified with the Didactic school of poets, of which Wordsworth was the principal exponent.
