The followers of Bardaisan (the Bardaisanites) continued his teachings in a sect of the 2nd century deemed heretical by later Christians. Bardaisan's son, Harmonius, is considered to have strayed farther from the path of orthodoxy. Educated at Athens, he added to the Babylonian astrology of his father Greek ideas concerning the soul, the birth and destruction of bodies and a sort of metempsychosis.
