Who they were
At Heraclea in Thrace, St. Sebastiana, martyr. She had been converted to the faith of Christ by the Apostle St. Paul. At the time of the Emperor Domitian and the governor Sergius, her faith was tested in many ways; finally, she was killed by the sword.
The miracles
There was never a formal cause: she has been honoured as a saint since before the Church's formal processes began.
Why that counted as sanctity
The Dominican Martyrology (1955) remembers her on 16 September.
