Abstract: The paper is concerned with the Italian writer Lorenzo Magalotti (1637-1712) and his relationship with the milieu of free-thinkers he encountered during three long travels through Europe (Spinoza and Saint-Évremond were among his acquaintances). In his Letters on atheism (published posthumously in 1719) Magalotti presented himself as an eloquent advocate of Catholicism, but it is not difficult to find in his pages a non-orthodox view of religion, the author being attracted to contemporary deism.
