P. B. Shelley, George William Tighe, and the Irish Roots of ‘The Sensitive-Plant’

This essay investigates the literary exchanges between the Irish poet and agronomist George William Tighe and Percy Bysshe Shelley in Pisa, where the former lived with Margaret King Mount Cashell, alias ‘Mrs Mason’, a radical Irish writer and former pupil of Mary Wollstonecraft. After moving to Pisa in 1820, Shelley began daily visits to the Mason-Tighe household, sourcing from Tighe's library a wealth of reading material on agricultural chemistry and botany, alongside Irish political and historical titles. Tighe's previously unexamined papers showcase his interests in Irish and Italian literature, republicanism, botany, and agriculture and reveal his links with the Lunar Society of Birmingham. Taking as a case study the first poem Shelley composed in Pisa, I argue that Tighe's agricultural pursuits shaped Shelley's political and botanical imagination in ‘The Sensitive-Plant’ and exerted a significant influence on Shelley's later poetry as a whole.
