The Ring and the Book, Browning's 21,000 line epic, is widely regarded as his masterpiece. This is the third, and final, volume of the Oxford edition covering this work, comprising the monologue of Johannes-Baptista Bottinius, and then the glowing conclusion to the work as a whole: the monologues of Pope Innocent XII and of Guido in his prison-cell prior to execution, and then the witty, ironic envoi of Book XII. The commentary in this edition contains a wealth of new contextual material that illuminates Browning's work in sometimes surprising ways. The copy text of 1888-9, the final edition of Browning's lifetime, has been scrupulously examined, both in relation to compositors' errors, and Browning's own final corrections to the text: eighty-nine emendations to accidentals, and nineteen emendations to substantives, produce a text as near as possible to Browning's final intentions. Appendix A presents previously unknown source material, concerning the 'cadaver synod' of 897, from Browning's father's historical notebooks. The Afterword gives a fresh view of the real history of the Franceschini murder case, based on new research in the archives in Arezzo.

This is the second instalment of Browning's great murder-story set in the Italy of the 1690s, The Ring and the Book, a poem which Henry James called a 'monstrous magnificence'. Here Browning lets the central characters of his poem - the corrupt aristocrat and murderer Franceschini, his victim, and her rescuer - tell the story in their own words.
