ABSTRACT
This chapter aims to trace the roles of Catherine of Siena and Birgitta of Sweden within the Observant Reform Movement. After having described the particular modes of the transmission of their mystical works, i.e. respectively the Dialogue and the Revelations, the author focuses on some significant manuscripts from the Italian peninsula and on a few key-figures, both men and women—Alfonso Pecha of Jaén, Cristoforo di Gano Guidini, Tommaso da Siena, Chiara Gambacorta, the Birgittine nuns of Paradiso in Florence and Syon in England among others— in order to demonstrate that there was a fluid context of exchanges between Birgittine and Catherinian circles.
