It's dutyful to remember that the transfer of a small part of the body of St. Ubaldo to
city of the region of Alsace in France.
A legend says that when St. Ubaldo was alive, he told his servant, who was originally from Northern Europe, that when he died he could have his episcopal ring. The servant did what he was told to do, but instead of pulling off the ring, he pulled away the whole thumb. The servant was shocked, and kept the relic as a treasure. He hid it in the knob of his stick, and returned to his hometown on foot.
After about a year, on the 30th June 1161, he reached the valley where Thann now is. It was a very hot day and he was very tired, so he put the stick near a tree and fell asleep in the shade of a fir tree. When he woke up, he wanted to continue his walk, but couldn't manage to pull the stick off the ground. In the meantime Count Enghelhard from his castle saw three flames coming out of the top of the tree without the tree burning and he immediately ran to see what was happening. There he found a man praying in front of his stick. The servant told his story and the count, who interpreted the fact as a divine sign, promised to build a small church to preserve that relic. After that the stick immediately came loose from the ground.
This is the legend, but the rest of the story confirms it, al least in the facts. The chapel really was constructed, after that the first houses were built, and the city of Thann was born. The inhabitants have always celebrated the founding of their city on the 30th of June. Two centuries later the actual church was constructed, the
"Collégiale de St.Thiébaut"
a splendid example of gothic art, where the relic of St. Ubaldo is conserved, a relic which since 1975 we know for sure to be part of St. Ubaldo's little finger of his right hand
and not his thumb, as the legend said.
St.Ubaldo is object of great cult at Thann, even if the name has been changed to: Thièbaut (Teobaldo) probably because the name Ubaldo, unknown in the germanic zone, sounded like the diminutive of Teobaldo. The devotion to St. Ubaldo created great ties between Thann and Gubbio, to the point that the people of Thann usually say: "Thann est la fille aînee de Gubbio"
(Thann is the eldest daughter of Gubbio)
