"To Mrs Siddons" was written by Samuel Taylor Coleridge and published in the 29 December 1794 Morning Chronicle as part of the Sonnets on Eminent Characters series. It describes Sarah Siddons, an actress Coleridge became fond of during his visits to London during college. The poem celebrates watching Siddons perform her various roles on stage. The actual authorship of the poem is uncertain, since it was attributed to Charles Lamb in various works. It is possible that Lamb and Coleridge worked on the poem together, and, if so, it would be one of Lamb's earliest works.
