This essay concerns the issue of the epistolary relationship documented by three pseudo-letters, traditionally ascribed to Saint Francis of Paola and sent to Savonarola. After having described the Florentine documentary context and having identified the main medium of transmission of the tradition in the Vita of Pseudo-Burlamacchi (first half of the XVIth century), it analyzes the content features, with special reference to two binomials: the Savonarolan Movement-the Medicean achievement and the acknowledgment-disavowal of Savonarola. At the end, the essay deals with the tradition of the letters from the beginning of the XVIIth century to the censorial interference by the Index Congregation (1659), noticing the insert of components from the Order of Minims on the until then prevalent Savonarolan feature, during the transition from manuscript to printed circulation
