On the first leaf is the following notation in pencil: "Gio. Btta Regni (Begni?) carcerato settimane in secreta il Lottis Balagi," indicating that Regni was either the author or the copyist.
Since no author's name is given in this ms., it is difficult to establish whether this play is by Onofrio Gilberto di Solofra (printed in Naples, 1653) which as Belloni states in his Il Seicento (p. 290) has thus far been unprocurable; or whether it is by Andrea Perrucci, a poet from Palermo, and a translator of Spanish comedies, who published a Convitato di Pietra in 1678, reprinted 1684, and perhaps later. The first Italian imitator of Tirso's Burlador is supposed to be Giacinto Andrea Cicognini (1606-1660); his Convitato di Pietra like our ms. also contains some Uscene buffonesche, but the comic characters have different names. At any rate, this ms. is important in regard to the literary vicissitudes of the Don Juan legend in Italy.
