Volterra still lacked a proper indoor performance stage in the early nineteenth century.
The main curtain (sipario) was painted by Nicola Contestabili, who represented Aulus Persius Flaccus, a Roman satirist and playwright born in Volterra, being led by the muses to the summit of Parnassus, ruled by Apollo.
The ceiling over the seats was painted with Venus in a chariot drawn by swans, and the parapets, with cupids, garlands and vignettes, harmonizing with the curtain.
In 1820, a group of 60 prominent citizens formed the Academy of the Riuniti (of the reunited), and purchased the entire theater, assigning to each member property of the individual boxes and seats, and this organization has continuously maintained that theatrical activity.
The theater was closed for physical repairs for 15 years, from 1984 to 1999, before the reopening, members donated their ownerships of seats and boxes to the academy.
