James Thomson, the writer of The City of Dreadful Night.
"Mr Browning is proud to remember," we are told by Mrs Orr, "that Mazzini informed him he had read this poem to certain of his fellow exiles in England to show how an Englishman could sympathise with them."—Handbook 2nd ed., p. 306.
Some curious particulars are recorded in reference to the composition of this poem. "The Flight of the Duchess took its rise from a line—'Following the Queen of the Gipsies, O!' the burden of a song which the poet, when a boy, heard a woman singing on a Guy Fawkes' day. The poem was written in two parts, of which the first was published in Hood's Magazine, April, 1845, and contained only nine sections. As Mr Browning was writing it, he was interrupted by the arrival of a friend on some important business, which drove all thoughts of the Duchess and the scheme of her story out of the poet's head. But some months after the publication of the first part, when he was staying at Bettisfield Park, in Shropshire, a guest, speaking of early winter, said, 'The deer had already to break the ice in the pond.' On this a fancy struck the poet, and, on returning home, he worked it up into the conclusion of The Flight of the Duchess as it now stands."—Academy, May 5, 1883.
