Saint Gatian - First Bishop of Tours (First Century).
Saint Gatian, a disciple of the Apostles and the first bishop of Tours. He left the city, however, and established a sort of headquarters in a rude grotto surrounded by thorn bushes. There he celebrated the divine mysteries. He traveled in the area accompanied by his disciples, to preach and to exercise mercy. The Cathedral of Tours still possesses a few fragments of his relics, which Saint Martin had placed in that principal Church.
