Who they were

In the Val di Non in Trentino, the holy martyrs Sisinnius, deacon, Martyrius, lector, and Alexander, porter: Cappadocians by origin, they founded a church in this region and introduced the use of hymns of praise to the Lord, and were then killed by some pagans who were offering sacrifices of purification.

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 Roman Martyrology remembers him on 29 May as a deacon from Cappadocia who founded a church in the Val di Non and was killed by pagans.
