The Most Assertive Saint?

From the today's Roman Martyrology:

At Brescia, St. Dominator, bishop.

Who's that?

The fourteenth bishop of Brescia, Italy. He served Brescia in the much troubled era following the final collapse of the Roman Empire in the West and at a time when Germanic tribes were in full control of Italy.

St. Dominator, ora pro nobis. St. Dominator, deprecare Dominum Deum.
