Opera in one act to a libretto by Giovacchino Forzano, third panel of The triptych. First performance: New York, Metropolitan Opera House, 14 December 1918.

For the comic panel of The triptych Forzano takes his inspiration from the XXX canto of the Inferno. One of the characters encountered is Gianni Schicchi, damned for having replaced Buoso Donati il Vecchio, whose legacy, as he was extremely rich, dying without direct heirs and without drawing up a will, would have been forfeited by the city of Florence. Gianni Schicchi, a friend of one of the relatives of the old man, hiding in the bed with the clothes of the dead body and in the presence of a notary, pretending to be Buoso, dictates his will in favour of the relative and himself.
The work was composed in a relatively short space of time, from October 1917 to April 1918.

Gianni Schicchi, of the works of The triptych, is the one most liked by audiences, for its popular and comical accents.
