In 1812 Peacock published another elaborate poem, "The Philosophy of Melancholy", and in the same year made the acquaintance of Shelley. He wrote in his memoir of Shelley, that he "saw Shelley for the first time just before he went to Tanyrallt", whither Shelley proceeded from London in November 1812 (Hogg's "Life of Shelley", vol. 2, pp. 174, 175.) Thomas Hookham, the publisher of all Peacock's early writings, was possibly responsible for the introduction. It was Hookham's circulating library which Shelley used for many years, and Hookham had sent "The Genius of the Thames" to Shelley, and in the "Shelley Memorials", pp. 38–40, is a letter from the poet dated 18 August 1812, extolling the poetical merits of the performance and with equal exaggeration censuring what he thought the author's misguided patriotism. Peacock and Shelley became friends and Peacock influenced Shelley's fortunes both before and after his death.
