Missionary and Literary Labors
Nahum belonged to the circle of disciples gathered around Cyril and Methodius, the brothers from Thessalonica who devised a written alphabet for the Slavs and translated the Scriptures and services into the Slavonic language. The tradition associates Nahum and his companions with the spread of this written culture, and he is named among those connected with the development of the Glagolitic and, later, Cyrillic scripts. When the disciples were driven from Great Moravia after the death of Methodius, several of them, Nahum among them, made their way to the Bulgarian lands, where the work of Slavonic letters could continue under more favorable conditions.
In Bulgaria Nahum was active in the schools that arose to train clergy and copy the sacred books, working first in the region of Plisk (Pliska) and afterward at Ochrid. There, alongside Saint Clement, he taught, preached, and led a body of scholars engaged in translating and transcribing the Scriptures. His labors at Ochrid placed him at the heart of the early flowering of Slavonic Christian letters in the Balkans.
