St Galgano was a ruthless crusader knight who had an apparition of st. Michael the archangel on his way back from the crusades. The angel instructed him to amend his life, at which he replied that it would be easier for him to put his sword through solid rock than amend his life, and to prove his point he struck the rock with his sword, while in ecstasy the sword went right through to the hilt, and still remains in Tuscany Italy today. He decided to become a hermit in imitation of a local saint of the region, but had tremendous pressure from his family not too. His mother especially wanted him to get married and played matchmaker with the most beautiful woman of the entire region. Inclined he agreed to go visit her, but on the way his horse refused to take the road, at which point the horse carried him up a hill where he had an apparition of the Apostles and the Holy Family. At this point he built his hermitage and died the following year. The year he died is the year St. Francis of Assisi was born. He personally met the Pope and was gifted the relics of st. Sebastian, and he was the first time the Vatican officially investigated the life of a saint. An audio book translated from an earlier work, was done by a community called Militia Templi, and can easily be found on Google. It is worth taking the hour or so too listen to it. Experts agree that it is plausible that Galgano's sword is responsible for the legend of the sword in the stone which merged during the medieval period with earlier legends of King Arthur.
However he does not have a novena prayer, nor is he a patron saint of anything...the outrage!!!!
