Saint Naum of Ochrid, a Bulgarian by descent, was one of the disciples of the holy Equals of the Apostles Cyril and Methodius (May 11), and he accompanied Saint Clement of Ochrid (July 27) when he preached the Gospel in Bulgaria. When Saint Clement set off to the southwestern regions, Saint Naum remained in the then capital city of Plisk. Afterwards Saint Naum succeeded Saint Clement in a monastery on the shores of Lake Ochrida, where he labored for ten years.

Saint Naum reposed on December 23, 910, and his relics were glorified by numerous miracles, especially healings of spiritual infirmities. The memory of the saint is also celebrated on December 23.
