INTRODUCTION TO THE PRISONER OF CHILLON.
The Prisoner of Chillon, says Moore (Life, p. 320), was written at Ouchy, near Lausanne, where Byron and Shelley "were detained two days in a small inn [Hôtel de l'Ancre, now d'Angleterre] by the weather." Byron's letter to Murray, dated June 27 (but ? 28), 1816, does not precisely tally with Shelley's journal contained in a letter to Peacock, July 12, 1816 (Prose Works of P. B. Shelley, 1880, ii. 171, sq.); but, if Shelley's first date, June 23, is correct, it follows that the two poets visited the Castle of Chillon on Wednesday, June 26, reached Ouchy on Thursday, June 27, and began their homeward voyage on Saturday, June 29 (Shelley misdates it June 30). On this reckoning the Prisoner of Chillon was begun and finished between Thursday, June 27, and Saturday, June 29, 1816. Whenever or wherever begun, it was completed by July 10 (see Memoir of John Murray, 1891, i. 364), and was ready for transmission to England by July 25. The MS., in Claire's handwriting, was placed in Murray's hands on October 11, and the poem, with seven others, was published December 5, 1816.
In a final note to the Prisoner of Chillon (First Edition, 1816, p. 59), Byron confesses that when "the foregoing poem was composed he knew too little of the history of Bonnivard to do justice to his courage and virtues," and appends as a note to the "Sonnet on Chillon," "some account of his life ... furnished by the kindness of a citizen of that Republic," i.e. Geneva. The note, which is now entitled "Advertisement," is taken bodily from the pages of a work published in 1786 by the Swiss naturalist, Jean Senebier, who died in 1809. It was not Byron's way to invent imaginary authorities, but rather to give his references with some pride and particularity, and it is possible that this unacknowledged and hitherto unverified "account" was supplied by some literary acquaintance, who failed to explain that his
