Foremost among my scholarly helpers at home has been my friend Professor W. P. Ker. For information and suggestions in answer to enquiries of one kind or another I am indebted to Professor Israel Gollancz and Mr Henry Bradley; to Professor Ernest Weekley, the best living authority on surnames; to Mr A. H. Bullen; to Mr Falconer Madan and Mr J. W. Mackail; to Mr Thomas J. Wise; to Mr H. C. Shelley; to Mr J. D. Milner, Director of the National Portrait Gallery; and to my former colleague Mr A. H. Smith, Keeper of Greek and Roman Antiquities at the British Museum. Mr George Whale supplied me with full copies of and comments on the entries concerning Keats in the books of Guy's Hospital. Dr Hambley Rowe of Bradford put at my disposal the results, unfortunately not yet conclusive, of the researches made by him as a zealous Cornishman on Keats's possible Cornish descent. I must not omit thanks to Mr Emery Walker for his skill and pains in preparing the illustrations for my book. With reference to these, I may note that the head from the portrait painted by Severn in 1859 and now in Lord Crewe's possession was chosen for colour reproduction as frontispiece because it is the fullest in colouring and, though done from memory so long after the poet's death, to my mind the most satisfying and convincing in general air of any of the extant portraits. Of the miniature done by Severn from life in 1818, copied and recopied by himself, Charles Brown and others, and made familiar by numberless reproductions in black and white, the original, now deposited by the Dilke Trustees in the National Portrait Gallery, has the character of a monochrome touched with sharp notes or suggestions of colour in the hair, lips, hands, book, etc. I have preferred not to repeat either this or the equally well known--nay, hackneyed--and very distressing death-bed drawing made by Severn at Rome. The profile from Haydon's life-mask of the poet is taken, not, like most versions of the same mask, from the plaster, but from an electrotype made many years ago when the cast was fresh and showing the structure and modellings of the head more subtly, in my judgment, than the original cast itself in its present state. Both cast and electrotype are in the National Portrait Gallery. So is the oil-painting of Keats seated reading, begun by Severn soon after the poet's death and finished apparently two years later, which I have reproduced, well known though it is, partly for its appositeness to a phrase in one of his letters to his sister. Besides the portraits of Keats, I have added from characteristic sources those of the two men who most influenced him at the outset of his career, Leigh Hunt and Haydon. A new feature in my book is provided by the reproductions of certain works of art, both pictures and antiques, which can be proved or surmised to have struck and stimulated his imagination. The reproductions of autographs, one of his own and one of Haydon's, speak for themselves.
