A religious sect of the 14th century belonging to the Greek Church; consisted chiefly of a community of monks who dwelt at Mount Athos; they professed a kind of Quietism (q. v .), and were noted for their practice of sitting for hours daily with their eyes fixed upon the navel (regarding the stomach as the seat of the soul); in this position they professed to see a divine light beaming out upon them, and to enjoy therein a specially intimate communion with God. See Athos, Mount .
