The Cenci, A Tragedy, in Five Acts (1819) is a verse drama in five acts by Percy Bysshe Shelley written in the summer of 1819, and inspired by a real Italian family, the Cenci (in particular, Beatrice Cenci, pronounced CHEN-chee). Shelley composed the play at Rome and at Villa Valsovano near Livorno, from May to 5 August 1819. The horrific tragedy, set in 1599 in Rome, of a young woman executed for pre-meditated murder of her tyrannical father, was a well-known true story handed down orally and documented in the Annali d'Italia, a twelve-volume chronicle of Italian history written by Ludovico Antonio Muratori in 1749. The events occurred during the Pontificate of Pope Clement VIII. Shelley was first drawn to dramatise the tale after viewing Guido Reni's portrait of Beatrice Cenci, a painting that intrigued Shelley's poetic imagination.
