Assedio delle ceneri is a cycle of sermons centered on the homonymous baroque form of Jesuit tradition. The cycle is composed of two texts chosen from the repertoire of Giacomo Lubrano, active in the second half of the seventeenth century, and nine other texts commissioned to five intellectuals: the economist Luciano Barca, the architect Stefano Boeri, the sociologist Alessandro Dal Lago, the writer Luca Doninelli and the mathematician Piergiorgio Odifreddi, and four poets: Jolanda Insana, Tommaso Ottonieri, Patrizia Valduga, Lello Voce.
The Jesuit sermon was a form of prayer widespread in the seventeenth-eighteenth century, had as its object the admonition of the faithful from sins but also from the abuse of mankind over Nature, a condition that would lead humanity to destruction. It is not difficult to trace references to ecological disaster and the (proto)capitalist threat. These are the themes that most suggest the need for analogies and admonitions regarding the risks faced by contemporary societies. Renato Quaglia, artistic director of the first edition of Napoli Teatro Festival Italia, commissions to the nine artists the “neopredics” of Assedio delle Ceneri.
