The Triumph of Life was the last major work by Percy Bysshe Shelley before his death in 1822. The work was left unfinished. Shelley wrote the poem at Casa Magni in Lerici, Italy in the early summer of 1822. He modelled the poem, written in terza rima, on Petrarch's Trionfi and Dante's Divine Comedy. Shelley was working on the poem when he accidentally drowned on 8 July 1822 during a storm on a voyage from Leghorn.
