William Hazlitt in the context of "Literary canon"

The Duenna is a three-act comic opera, mostly composed by Thomas Linley the elder and his son, Thomas Linley the younger, to an English-language libretto by Richard Brinsley Sheridan. At the time, it was considered one of the most successful operas ever staged in England, and its admirers included Samuel Johnson, William Hazlitt and George Byron (the latter called it "the best opera ever written").

First performed in the Covent Garden Theatre on 21 November 1775, The Duenna was performed seventy-five times in its first season, and was frequently revived in Britain until the 1840s. In total, 256 performances of the opera had been held in London from its opening in 1775 to the end of the 18th century. Another 194 performances occurred in the capital during the 19th century, with the last known London staging happening in January 1851 (there were some subsequent Dublin performances in 1853). The opera was first performed in the Colony of Jamaica in 1779, and subsequently spread round the English-speaking world. Soon after its first London performance, representations sprang up in British provincial theatres, though these often used invented dialogue (Sheridan's original text was not published until 1794) to link the published songs and musical numbers. In Autumn 2010, English Touring Opera performed the complete opera in venues around the UK, beginning in the Linbury Studio Theatre within the Royal Opera House as part of ROH2's Autumn season – bringing the opera back to its Covent Garden home. Two modern operas based on Sheridan's libretto have been performed: Sergei Prokofiev's Betrothal in a Monastery (composed 1940–1), and Roberto Gerhard's version of 1945–7.

Sarah Siddons (née Kemble; 5 July 1755 – 8 June 1831) was a Welsh actress, the best-known tragedienne of the 18th century. Contemporaneous critic William Hazlitt dubbed Siddons as "tragedy personified".

She was the elder sister of John Philip Kemble, Charles Kemble, Stephen Kemble, Ann Hatton, and Elizabeth Whitlock, and the aunt of Fanny Kemble. She was most famous for her portrayal of the Shakespearean character Lady Macbeth, a character she made her own.

Charles Lamb (10 February 1775 – 27 December 1834) was an English essayist, poet, and antiquarian, best known for his Essays of Elia and for the children's book Tales from Shakespeare, co-authored with his sister, Mary Lamb (1764–1847).

Friends with such literary luminaries as Samuel Taylor Coleridge, Robert Southey, William Wordsworth, Dorothy Wordsworth and William Hazlitt, Lamb was at the centre of a major literary circle in England. He has been referred to by E. V. Lucas, his principal biographer, as "the most lovable figure in English literature".

Imogen (also spelled Innogen) is the daughter of King Cymbeline in Shakespeare's play Cymbeline. She was described by William Hazlitt as "perhaps the most tender and the most artless" of all Shakespeare's women.

James Henry Leigh Hunt (19 October 1784 – 28 August 1859), best known as Leigh Hunt, was an English critic, essayist and poet.

Hunt co-founded The Examiner, a leading intellectual journal expounding radical principles. He was the centre of the Hampstead-based group that included William Hazlitt and Charles Lamb, known as the "Hunt circle". Hunt also introduced John Keats, Percy Bysshe Shelley, Robert Browning and Alfred Tennyson to the public.

Polonius is a character in William Shakespeare's play Hamlet. He is the chief counsellor of the play's ultimate villain, Claudius, and the father of Laertes and Ophelia. Generally regarded as wrong in every judgment he makes over the course of the play, Polonius is described by William Hazlitt as a "sincere" father, but also "a busy-body, [who] is accordingly officious, garrulous, and impertinent". In Act II, Hamlet refers to Polonius as a "tedious old fool" and taunts him as a latter day "Jephtha".

Polonius connives with Claudius to spy on Hamlet. Hamlet unknowingly kills Polonius, provoking Ophelia's descent into madness, ultimately resulting in her (probable) suicide and the climax of the play: a duel between Laertes and Hamlet.
