Galgano Guidotti was a 12th-century knight from Chiusdino, located in modern-day Tuscany. Born in 1148 to a feudal family, he reportedly lived a worldly life before undergoing a spiritual conversion. Following a vision on Monte Siepi, he abandoned his knighthood to live as a hermit. He died in 1181 at the age of 33. He is recognized as a saint in both the Catholic and Anglican traditions, and his life is famously associated with a sword embedded in rock.
