Sethian Gnosticism

A German scholar identified this specific grouping as a coherent single corpus only in 1974 — the name 'Sethianism' is a modern academic category, not a term any ancient group used of itself. A separate ancient source does independently confirm that some of these very texts were being read and debated in a Roman philosopher's own circle in antiquity.
