["Epipsychidion" was composed at Pisa, January, February, 1821, and published without the author's name, in the following summer, by C. & J. Ollier, London. The poem was included by Mrs. Shelley in the "Poetical Works", 1839, both editions. Amongst the Shelley manuscripts in the Bodleian is a first draft of "Epipsychidion", 'consisting of three versions, more or less complete, of the "Preface [Advertisement]", a version in ink and pencil, much cancelled, of the last eighty lines of the poem, and some additional lines which did not appear in print' ("Examination of the Shelley manuscripts in the Bodleian Library, by C.D. Locock". Oxford, Clarendon Press, 1903, page 3). This draft, the writing of which is 'extraordinarily confused and illegible,' has been carefully deciphered and printed by Mr. Locock in the volume named above. Our text follows that of the editio princeps, 1821.]
