The life of Sergius and Herman of Valaam
Together the two founded a monastery on the island of Valaam, then still a place of old pagan worship where local elders kept up rites at a site used for sacrifice. Sergius is remembered as having settled first alone in a cave on the island, from where, unarmed and living among a hostile population, he began to preach and, over time, to baptize its inhabitants; Herman joined him, and together they gathered the community that grew into the monastery. Their work reached beyond the island itself, helping to root Orthodoxy among the Karelian Finns of that borderland, a people who had also endured pressure from Swedish Catholic rule nearby. Both reposed around 1353, though even that date, like the founding of their monastery itself, cannot be fixed with full confidence from the historical record, and scholars have proposed dates for Valaam's founding ranging across five centuries. Their relics remain on Valaam to this day, and the monastery they began has drawn pilgrims from across the Orthodox world ever since.
