Works & Achievements

The Dialogue of Divine Providence (1378)

Catherine's spiritual masterpiece, dictated in ecstasy to her secretaries, taking the form of a dialogue between the soul and God. Translated into Latin as early as the 15th century, it is considered one of the great mystical texts of the Middle Ages.

Letters (Epistolario) (1370–1380)

A collection of 382 letters addressed to popes, kings, condottieri, clergy, and ordinary believers, written in vernacular Tuscan. Remarkable for their candor and eloquence, these letters offer a unique window into the politics and spirituality of the 14th century.

Prayers (Orationi) (1376–1380)

A collection of 26 prayers uttered by Catherine during her ecstasies and transcribed by her secretaries. They reveal the depth of her inner life and her theology centered on the blood of Christ.

Anecdotes

Catherine of Siena learned to read on her own — miraculously, according to her contemporaries — as an adult. She dictated all her correspondence and writings to secretaries before she herself acquired the ability to write, which those close to her considered a divine gift.

At the age of seven, Catherine reportedly had her first vision of Christ in glory above the Dominican church in Siena. This mystical experience shaped her entire life: she immediately made a vow of virginity, despite her parents' wishes to see her married.

In 1375, Catherine received the stigmata of Christ during an ecstasy in Pisa. She prayed that they remain invisible during her lifetime to avoid vanity, and it is said that the pain remained without the marks being visible to others.

To persuade Pope Gregory XI to leave Avignon, Catherine wrote him letters of striking frankness, calling him 'the sweet Christ on earth' while rebuking him for his timidity. This boldness from a simple craftswoman addressing the supreme pontiff was remarkable for the era.

Catherine died in Rome at only 33, worn out by prolonged fasting and austerities. In her final weeks, she could no longer swallow any food and spent her days in prayer for the unity of the Church — at the very moment when the Great Schism was tearing Christendom apart.

I beg you, I beg you, sweet Father, in the name of Christ crucified, not to be afraid; but come, come and fight the enemies of God. Be courageous, and not a coward.
