He composed five of his six great odes at Wentworth Place in April and May and, although it is debated in which order they were written, "Ode to Psyche" opened the published series. According to Brown, "Ode to a Nightingale" was composed under a plum tree in the garden. Brown wrote, "In the spring of 1819 a nightingale had built her nest near my house. Keats felt a tranquil and continual joy in her song; and one morning he took his chair from the breakfast-table to the grass-plot under a plum-tree, where he sat for two or three hours. When he came into the house, I perceived he had some scraps of paper in his hand, and these he was quietly thrusting behind the books. On inquiry, I found those scraps, four or five in number, contained his poetic feelings on the song of our nightingale." Dilke, co-owner of the house, strenuously denied the story, printed in Richard Monckton Milnes' 1848 biography of Keats, dismissing it as 'pure delusion'.
