Saint Fantinus the Wonderworker was born in Calabria (Italy) of parents George and Vriena. He was given over to a monastery, and from childhood he was accustomed to ascetic deeds. In his youth he wandered into the wilderness, remaining often without food or clothes for twenty days. The monk spent 60 years in such exploits.
Before the end of his life, fleeing before pursuing Saracens, he went with his disciples Vitalius and Nicephorus to the Peloponnesos (Greece). Preaching the way of salvation, the monk visited Corinth, Athens, Larissa and Thessalonica, where he venerated the relics of the Great Martyr Demetrius (October 26). He died peacefully in extreme old age at the end of the ninth, and beginning of the tenth century.
