Note 330 — THE AGE OF BRONZE.

[Robert Stewart, Viscount Castlereagh, afterwards Marquis of Londonderry (1769-1822), who had been labouring under a "mental delirium" (Letter of Duke of Wellington, August 9, 1822), committed suicide by cutting his throat with a penknife (August 12, 1822). He was the uncompromising and successful opponent of popular causes in Ireland, Italy, and elsewhere, and, as such, Byron assailed him, alive and dead, with the bitterest invective. (See, for instance, the "Dedication" to Don Juan, stanzas xi.-xvi., sundry epigrams, and an "Epitaph.") In the Preface to Cantos VI., VII., VIII., of Don Juan, he justifies the inclusion of a stanza or two on Castlereagh, which had been written "before his decease," and, again, alludes to his suicide. (For an estimate of his career and character, see Letters, 1900, iv. 108, 109, note 1; and for a full report of the inquest, The Annual Biography, 1823, pp. 56-62.)]
