Saint Maturinus, or Mathurin (died ca. 300 AD) was a French exorcist and missionary venerated as a saint.
The first source to mention Maturinus is the Martyrology of Usuard, written in 875. In the next century, a biography of Maturinus was composed. According to his legend, Maturinus was born in Larchant. His parents, Marinus and Euphemia, were pagan. His father was entrusted by Maximian with the task of exterminating the Christians of the region.
His son Maturinus, however, was secretly baptized by Polycarp, when the boy was twelve. According to legend, he began to perform miracles, drive out demons, and calm rowdy or riotous individuals. He eventually converted his parents to Christianity.
He became a priest at the age of twenty, and took care of the diocese when the local bishop went to Rome.
His fame grew, and the emperor himself requested that he come to Rome so that his daughter-in-law Flavia Maximiana Theodora, who had been possessed by an evil spirit, could be cured by the saint. The demon in Theodora’s body was expelled. Maturinus lived for three more years in Rome, interceding with the emperor on behalf of persecuted Christians. He died on November 1, and was buried in a Roman cemetery. However, Maturinus miraculously indicated that he wished to be buried in Larchant; his body was taken to Sens and then to Larchant.
