He is also mentioned in a sermon on Psalm 118 by 4th-century bishop Ambrose of Milan (Saint Ambrose): in his sermon, Ambrose stated that Sebastian came from Milan and that he was already venerated there at that time.

The oldest record of the details of Sebastian's martyrdom is found in the Chronograph of 354, which mentions him as a martyr, venerated on January 20. He is venerated in the Catholic Church and the Orthodox Church. In all versions of the story, shortly after his recovery he went to Diocletian to warn him about his sins, and as a result was clubbed to death.
