Wordsworth wrote to Joseph Cottle in 1799:
From what I can gather it seems that the Ancient Mariner has upon the whole been an injury to the volume, I mean that the old words and the strangeness of it have deterred readers from going on. If the volume should come to a second Edition I would put in its place some little things which would be more likely to suit the common taste.
However, when Lyrical Ballads was reprinted, Wordsworth included it despite Coleridge's objections, writing:
The Poem of my Friend has indeed great defects; first, that the principal person has no distinct character, either in his profession of Mariner, or as a human being who having been long under the control of supernatural impressions might be supposed himself to partake of something supernatural; secondly, that he does not act, but is continually acted upon; thirdly, that the events having no necessary connection do not produce each other; and lastly, that the imagery is somewhat too laboriously accumulated. Yet the Poem contains many delicate touches of passion, and indeed the passion is every where true to nature, a great number of the stanzas present beautiful images, and are expressed with unusual felicity of language; and the versification, though the metre is itself unfit for long poems, is harmonious and artfully varied, exhibiting the utmost powers of that metre, and every variety of which it is capable. It therefore appeared to me that these several merits (the first of which, namely that of the passion, is of the highest kind) gave to the Poem a value which is not often possessed by better Poems.
