Who they were
At Chalcedon, the holy martyrs Sosthenes and Victor. In the persecution of Diocletian, under Priscus proconsul of Asia, these martyrs were chained and exposed to wild beasts. Surviving this ordeal, they were condemned to be burned alive. They saluted one another with a holy kiss, and, kneeling in prayer, gave up their souls to God.
The miracles
There was never a formal cause: he has been honoured as a saint since before the Church's formal processes began.
Why that counted as sanctity
The Dominican Martyrology (1955) remembers him on 10 September.
