Nebridius
"Nebridius" was also the name of a close friend of Augustine of Hippo, who is mentioned in his letters.
Saint Nebridius was bishop of Egara (Terrassa) (516–527) and then bishop of Barcelona from 540 to around 547 AD. His feast day falls on 9 February. A native of Girona, Nebridius, according to tradition, had three brothers who were also saints. They were Saint Justus, bishop of Urgell; Saint Elpidius; and Saint Justinian. He was very learned and wrote interpretations of the Scriptures. He also wrote a work called In cantica canticorum about the church chants. He was a Benedictine.
