Robertson by John Keats

This text isn't a poem by John Keats; it's a publisher's imprint — the bibliographic details that appear on the title page or colophon of a book published by Oxford University Press at the Clarendon Press in 1909, almost a century after Keats passed away. There's no poem to analyze here, just three lines indicating the place of publication, the press, and the year. To conduct a meaningful analysis, we would need the complete text of a poem.

No tone can be identified since there’s no poem included. The text provided is a bibliographic imprint.

John Keats (1795–1821) stood out as a key figure in English Romanticism, celebrated for his odes like "Ode to a Nightingale" and "To Autumn." He passed away from tuberculosis at just 25 years old. The Clarendon Press, which was established in Oxford during the 17th century, became a prominent publisher of scholarly editions of English literature. By 1909, it was releasing authoritative collected works of Romantic poets, including Keats. The text provided here seems to be the imprint page from one of these editions—likely E. de Sélincourt's 1905/1909 collection of Keats's poems—rather than a poem itself. Without the actual text of a poem, there's no room for literary analysis.
