Advertising doubt in early modern Italy: Doubt and ignorance in early modern paratexts

Spelled in several different ways, the word 'doubt', usually in the plural 'doubts' (dubbi, dubitazioni) appears on the frontispiece of several works printed in Venice and elsewhere in Italy in the sixteenth century. Building on different traditions, ranging from the pseudo-Aristotelian Problemata to Medieval didactic literature, these texts, normally in the vernacular, address questions that the average reader may have on a variety of topics: from thermal baths to indulgences, from natural philosophy to duel. While usually the term 'doubt' means 'question', things can be sometimes less straightforward, especially when it comes to religious texts or works penned by unorthodox writers, as in the case of Ortensio Lando's Quattro libri di dubbi. This article will explore paratextual elements of works addressing doubts focusing on a variety of topics such as readership, definitions of doubt and its function, the role of these works in the dissemination of knowledge.
