The Letters of St. Catherine of Siena
This book is in Italian.
The letters of St. Catherine of Siena (1347-1380) in Niccolò Tommaseo’s edition, edited by Piero Misciattelli (Siena 1913-1922), with the editor’s notes and summaries: to Raymond of Capua, to Gregory XI and Urban VI, to the Florentines, to her mother Lapa, to her disciples and many others. It holds the letters transcribed so far on Italian Wikisource (the Misciattelli numbering); the remaining letters of the epistolary are not yet imported. A selection in English is in the Scudder book of the same work.
