Galgano Guidotti (1148 – 3 December 1181)[a] was a Catholic saint from Tuscany born in Chiusdino, in the modern province of Siena, Italy.

An invisible angel lifted him to his feet and led him to Monte Siepi, a rugged hill close to his home town of Chiusdino.

To prove his point, he drew his blade and thrust at the stony ground, but the sword slid easily into the living rock, where it remains stuck fast to this day.

[12] In a season 7 episode of TV series, Forged in Fire, bladesmiths recreated "Excalibur", a medieval broadsword believed to be inspired by Galgano's story.

[13] An episode of Ancient X-Files examined the sword in the stone and the connections between it, St Galgano, Sir Gawain, and King Arthur.
