jats:pIn the early 1610s, some Italian Lutheran propaganda came to the attention of the Holy Office. Such propaganda is an anomaly for the period, and questions the current scholarship on the topic. Via the bibliographic study of pamphlets previously neglected or unknown, this article investigates this activity, mostly attributing it to Antonio degli Albizzi (1547–1627), sometime secretary to the Cardinal of Austria. This curious case elucidates the longevity of interest in Lutheranism in the Italian peninsula, and, even if in the mind of just one man, the belief that seventeenth-century Italians could still turn to Protestantism.</jats:p>
