She joined the Dominican third order in Siena in 1363 and soon became known for her holiness and severe asceticism. Catherine called for a Crusade against the Muslims as a means of calming domestic conflict in Italy. She also played a major role in returning the papacy from Avignon to Rome (see Avignon papacy). Her writings include four treatises on religious mysticism known as The Dialogue of St. Catherine.

original name  Caterina Benincasa  
born March 25, 1347, Siena, Tuscany
died April 29, 1380, Rome; canonized 1461; feast day April 29
 Dominican tertiary, mystic, and patron saint of Italy who played a major role in returning the papacy from Avignon (Avignon papacy) to Rome (1377). She was declared a doctor of the church in 1970 and a patron saint of Europe in 1999.

      Catherine became a tertiary (a member of a monastic third order who takes simple vows and may remain outside a convent or monastery) of the Dominican order (1363), joining the Sisters of Penitence of St. Dominic in Siena. She rapidly gained a wide reputation for her holiness and her severe asceticism. When the rebellious city of Florence was placed under an interdict by Pope Gregory XI (1376), Catherine determined to take public action for peace within the church and Italy and to encourage a crusade against the Muslims. She went as an unofficial mediator to Avignon with her confessor and biographer Raymond of Capua. Her mission failed, and she was virtually ignored by the Pope, but while at Avignon she promoted her plans for a crusade.

      It became clear to her that the return of Pope Gregory XI to Rome—an idea that she did not initiate and had not strongly encouraged—was the only way to bring peace to Italy and thus facilitate a crusade. Catherine left for Tuscany the day after Gregory set out for Rome (1376). At his request she went to Florence (1378) and was there during the Ciompi Revolt in June. After a short final stay in Siena, during which she completed her Dialogo (begun the previous year), she went to Rome in November, probably at the invitation of Pope Urban VI, whom she helped in reorganizing the church. From Rome she sent out letters and exhortations to gain support for Urban; as one of her last efforts she tried to win back Queen Joan I of Naples to obedience to Urban, who had excommunicated the Queen for supporting the antipope Clement VII.

      Catherine's writings, all of which were dictated, include about 380 letters, 26 prayers, and the 4 treatises of Il libro della divina dottrina, better known as the Dialogo (c. 1475; Eng. trans. by S. Noffke, 1980). The record of her ecstatic experiences in the Dialogo illustrates her doctrine of the “inner cell” of the knowledge of God and of self into which she withdrew. A complete edition of Catherine's works, together with her biography by Raymond, was published in Siena (1707–21).
