Who was the monk who ended the gladiator games?

According to the Church historian Theodoret, Saint Telemachus was a monk who] tried to stop a gladiatorial fight in a Roman amphitheatre, and was stoned to death by the crowd. The Christian Emperor Honorius was impressed by the monk's martyrdom and it spurred him to issue a ban on the gladiatorial games in the western part of the Roman Empire.

However, neither Saint Telemachus nor Honorius stopped the games. The games continued. Honorius issued another ban in 404. Valentinian III repeated the ban in 438. This time it seemed to be effective, mainly because the popularity of these games waned. Animal hunts, which had been part of the gladiatorial games, continued.
