In spite of the bad reviews of "Poems", Hunt published the essay "Three Young Poets" (Shelley, Keats, and Reynolds) and the sonnet "On First Looking into Chapman's Homer," foreseeing great things to come. He introduced Keats to many prominent men in his circle, including the editor of "The Times", Thomas Barnes; the writer Charles Lamb; the conductor Vincent Novello; and the poet John Hamilton Reynolds, who would become a close friend. He was also regularly meeting William Hazlitt, a powerful literary figure of the day. It was a decisive turning point for Keats, establishing him in the public eye as a figure in what Hunt termed "a new school of poetry." At this time Keats wrote to his friend Bailey: "I am certain of nothing but the holiness of the Heart's affections and the truth of the imagination. What imagination seizes as Beauty must be truth." This passage would eventually be transmuted into the concluding lines of "Ode on a Grecian Urn": Beauty is truth, truth beauty' – that is all / Ye know on earth, and all ye need to know". In early December 1816, under the heady influence of his artistic friends, Keats told Abbey that he had decided to give up medicine in favour of poetry, to Abbey's fury. Keats had spent a great deal on his medical training and, despite his state of financial hardship and indebtedness, had made large loans to friends such as painter Benjamin Haydon. Keats would go on to lend £700 to his brother George. By lending so much, Keats could no longer cover the interest of his own debts.
