Famed Irish poet and lyricist (1779–1852) best known for such verses as “The Last Rose of Summer” and “Believe Me If All These Endearing Young Charms.” ALS, one page, 7.25 x 9, August 24, 1831. Moore writes to Owen Rees, Esq. In part: “I fear you have not been able to get me Bossuet’s Histoire des Variations…. I see however that it is in Milliken’s catalogue with many other books which would be very useful to me for my present purpose, and as he was good enough to offer me the use of any I should want, I rather think I shall try him. I was in great hopes that my Lord Edward would succeed at last sufficiently to authorize my encroaching, with somewhat less remorse than I can do now, on the credit you allow me—but I fear that there is little more … from the sale…. I must now only work the harder at the tasks I have before me….” The adjacent page bears the integral address leaf. In fine condition, with early dealer’s catalogue entry affixed to upper left corner (well away from text), intersecting folds, and chips and tears to address leaf. R&R COA.
