Fantinus was a tenth-century Italian monk and hermit who lived approximately from 927 to 1000. Born in Calabria to parents named George and Vriena, he entered monastic life at thirteen and served as both a cook and a porter. He later lived as an ascetic hermit near Mount Mercurion, where he practiced extreme self-denial and spent his time copying manuscripts. Known as Fantinus the Younger to distinguish him from an earlier saint, he eventually traveled to Greece to preach following a divine instruction.
Monastic life

After establishing himself as a hermit, Fantinus influenced his parents and siblings, including his brothers Luke and Cosmas, to embrace monasticism. He functioned as a spiritual mentor to various disciples, such as Nilus the Younger. During his time in Calabria, he maintained a rigorous lifestyle, consuming only raw vegetables while dedicating himself to the preservation of texts through manual copying.
Travels in Greece
Following the destruction of his original monastery by raiders, Fantinus moved to Greece with two companions. During the journey, he reportedly transformed seawater into fresh water to sustain his group. He traveled through several cities, including Athens and Corinth, and spent time near Thessalonica. In these regions, he was recognized for healing the sick and providing spiritual guidance to various individuals.
Veneration
Recognized as a saint in Catholic and Orthodox traditions, he is commemorated on November 14. His life and experiences, including his ascetic practices and his travels, have been preserved in historical accounts and modern translations.
