St. Petronax (d. 747) was from Brescia, Italy, and joined the Benedictines.
In 717, he traveled to the ruins of an abbey at Monte Cassino. The hermits living in the ruins elected him as their superior.
The saint rebuilt the abbey and it once again became very famous. Many people either joined the order or wanted to visit because it was such a friendly and holy place.
We honor Petronax on May 6.
