 "Al Aaraaf" includes names Poe would later reuse: Ligeia and Zante. Some of the themes in the poem also foreshadow a future poem, "The City in the Sea" (1831). The critical failure of both "Al Aaraaf" and "Tamerlane" convinced Poe that long poems are inherently flawed because they cannot sustain a proper mood or a high quality poetic form. Because of this, he never again experimented with long poetry. He would later write of his theory on short poetry in "The Poetic Principle" in 1848. In that essay, he wrote "A long poem does not exist. I maintain that the phrase, 'a long poem,' is simply a flat contradiction in terms." Instead, he says, epic poetry and other long poems are actually a series of short poems strung together. Critics have suggested that this theory was written so that Poe could justify why "Al Aaraaf" was unpopular.
