Today the importance of epistolary networks for intellectuals in early modern Europe is well appreciated. Nevertheless, connections reaching outside the canon of celebrated humanists and scientists in the Republic of Letters are little studied. This article examines how Charles de Bovelles (1479–1567) used letters to establish a philosophical persona and publicize his contemplative approach to natural philosophy. Scrutinizing how Bovelles created an epistolary community comprising university alumni and men in religious professions, the article sheds new light on the culture of contemplation in the early sixteenth century.
