"The Neapolitan polygrapher also ventured into the field of short stories by writingIl Fuggilozio (Naples 1596, which was followed by numerous other editions). The setting is Boccaccio-esque: the interlocutors are eight gentlemen and two women who, meeting in the palace of the prior Ravaschiero, they decide to cheer up the patient by telling jokes, jokes and jokes in turn, the theme of which is fixed in advance, day by day, Fuggilozio lacks narrative breadth due to the excessive brevity of the stories and is linked to the collections the ambiguity of the book can be seen already in the first day, in which the theme of the licentiousness of women is developed, allowing Costo to recover the "obscene" repertoire of the Renaissance novel. an expressed sensuality is immediately attenuated and redeemed by the citation of an authoritative sentence and the author in the presentation urges readers to "not so much aim when reading this work at the ridiculous bark, as at its beneficial substance". It remains to be seen to what extent this exhortation responds to actual moralistic needs, or whether it does not constitute a cover to escape censorship." (Treccani online, sub vocis).
