Justina of Nicomedia
Christian martyr
Who they were
Cyprian and Justina were Christians of Antioch who, according to their legend, were beheaded at Nicomedia on 26 September 304, under Diocletian, on the bank of the river Gallus. The story says Cyprian was a pagan magician who used demons to try to ruin Justina, a Christian virgin, but she drove them off with the sign of the cross. In despair Cyprian made the sign of the cross himself, was freed, became a Christian and in time a bishop, while Justina became head of a convent.
The Catholic Encyclopedia treats this account as a legend, though an early one known to St. Gregory Nazianzen and Prudentius, and notes that no Bishop of Antioch was called Cyprian. The legend says their bodies were taken to Rome by Christian sailors and later placed in Constantine's basilica.
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
A Christian virgin of Antioch whose faith, in the old legend, turned a magician into a Christian.
