This medieval Latin work describes the extraordinary works of God through saints, particularly focusing on Saint Berach of Ireland, who emerged after Saint Patrick. Born to noble parents, Berach was destined for greatness as foretold by the holy man Fregius. He was baptized shortly after birth and raised under Fregius's guidance, excelling in both spiritual and intellectual pursuits. Berach's mission was to convert the idol-worshipping inhabitants of Ireland, illuminating their path towards the faith of Christ through miracles and teachings.
