 In the late third century, Sethianism was attacked by neo-Platonists like Plotinus, and Sethianism became alienated from Platonism.In the early- to mid-fourth century, Sethianism fragmented into various sectarian Gnostic groups such as the Archontics, Audians, Borborites, and Phibionites, and perhaps Stratiotici, and Secundians.Some of these groups existed into the Middle Ages.
