Living at the Oratory almost continuously until his death in 1890, his major works written in Birmingham include the autobiographical Apologia Pro Vita Sua, the novel Loss and Gain, his principal philosophical work Grammar of Assent, and the poem The Dream of Gerontius, later set to music by Edward Elgar. Under Newman the Oratory became the focus of a literary culture itself, attracting further Catholic writers of note. The poet Gerard Manley Hopkins taught at The Oratory School when he graduated and converted to Catholicism in 1867; it was here that he was to first develop the ideas of inscape and instress that were to prove central to his poetic practice.[96] The novelist, poet and polemicist Hilaire Belloc came from a long line of Birmingham radicals – his mother was Bessie Rayner Parkes, his grandfather Joseph Parkes and his great-great grandfather Joseph Priestley.
