1) She had a twin.
Though it’s not clear whether they were identical or not, St. Catherine had a twin sister, Giovanna. They were born prematurely when her mother was forty years old. Unfortunately, Giovanna died in infancy. Her mother had another child two years later and named that child Giovanna as well.
2) She had 24 siblings.
That’s right, she was one of 25 children. And yes, they were all from the same parents. Granted, only about half of them made it to adulthood (due to a high infant mortality rate), but still, that’s quite the family.
3) She had the nickname “Euphrosyne.”
She was so joyful as a child that her family called her “Euphrosyne,” Greek for “joy.”
4) She had a mystical vision of Jesus as a young child.
An early biography written by her confessor claimed that when she was 5 or 6 year old, she was walking home and suddenly had a vision of Jesus enthroned in heaven surrounded by the Apostles Peter, Paul, and John.
5) She had a mystical vision of St. Dominic.
The two most culturally accepted paths for a woman in her time and place were marrying or becoming a cloistered nun. St. Catherine resisted both options. Apparently, St. Dominic himself appeared to her in a vision, which convinced her to be a Dominican tertiary, something that at the time was normally reserved for widows. She also got special permission to wear a habit.
6) She experienced stigmata.
First reported to have been experienced by St. Francis of Assisi a little more than a hundred years earlier, St. Catherine received a version of the stigmata in 1375 that, according to the biography written by her confessor, was only visible to herself per her request of God.
7) She was very politically active, writing letters to rulers and clergy.
In her late 20s, she started dictating letters with scribes to various rulers and clergy, begging for peace between states and for the papacy to return to Rome from Avignon, France. She was so respected, she was sent on diplomatic peace missions by various governments.
8) She survived an assassination attempt.
In early 1378, she was sent by Pope Gregory XI to Florence, Italy to seek peace between Florence and Rome. Soon after, however, Pope Gregory XI and violence broke out. On June 18th, in the midst of violence, someone tried to assassinate her, though she survived.
9) She was attacked by demons on her deathbed.
Here’s what one eye-witness reported:
[S]he began altogether to change, and to make various signs with her head and her arms as if to show that she was suffering from grave assaults of demons, and remained in this calamitous state for an hour and a half, half of which time having been passed in silence…
10) She’s co-patroness of Rome, of Italy, and of Europe.
She was made co-patroness of Rome in 1866 by Pope Pius IX, co-patroness of Italy in 1939 by Pope Ven. Pius XII, and co-patroness of Europe in 1999 by Pope St. John Paul II. St. Catherine of Siena, please pray for us!
