There seems to have been at one time a regular manufactory for the production of letters by Shelley, Keats, and Byron. The market was swamped by cleverly forged documents. About twenty years ago, Robert Browning, the poet, edited a volume of letters by Shelley, and critics said that they would prove useful to all future biographers of that wayward genius. These letters turned out to be forgeries. One epistle was found to be a ‘crib’ from an article by Sir Francis Palgrave, in the ‘Quarterly Review.’ Another was slightly altered from a paper in a literary annual. When research was made, the discovery ensued that the supposed originals had been purchased by Mr. Moxon, the publisher, at an auction. The auctioneer had had them consigned to him by a bookseller in Pall Mall, and the bookseller had bought them from two unknown women, who looked as much like ladies as the letters looked like genuine productions. If Mr. Moxon had not sent a copy of the volume to Mr. Tennyson a long time might have elapsed before the fraud could have been discovered. But Mr. Palgrave, on a visit to the Laureate, happened to open the book, and his eye fell on a letter from Shelley to Godwin, written from Florence. Mr. Palgrave recognised in it a portion of an article on Florence, in the ‘Quarterly,’ written by his father, Sir Francis. Mr. Moxon called in all the copies of this volume of pseudo-epistles, and suppressed the publication altogether. A curious result has followed. The volume is worthless, but it is rare; and simply on account of its rarity it is set down in a London bookseller’s catalogue now before us at the price of 1_l._ 10_s._ Stray letters of Shelley continued to turn up in the market. Letters to his wife, of the most confidential nature, containing aspersions on his father, were bought by Sir Percy Shelley, the poet’s son. These too proved to be forgeries and were destroyed. Another letter, addressed to Byron, and bearing Shelley’s signature, contained an assertion against the fidelity of ‘Harriet.’ Whoever bought it paid six guineas for a calumny against a dead and defenceless woman, to which was appended the forged signature of her dead and defenceless husband. Forged letters purporting to be from Byron are, as it were, to be had at every turn. Also books with his alleged manuscript notes in the margin. Good judges assert that these notes and letters are written with a thorough knowledge of Byron’s life and feelings, and that the books are chosen with the most perfect knowledge of his tastes and peculiarities.
