Who they were

Diomedes the Younger was born at Leucopolis, in Cyprus, and lived in the 4th century, educated by the bishop Saint Triphyllius; he grew up virtuous and gifted with the power of miracles. When Cyprus was attacked by Saracen raiders, tradition says he made the sign of the cross over them and, rather than overpowering them, converted them to Christianity. He died on 28 October, the day on which he is still honoured, and a church soon rose in his memory that remains a place of pilgrimage.

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

Cypriot saint educated by Saint Triphyllius, said to have converted Saracen raiders with the sign of the cross; feast 28 October.
