Type: parallel / comparative argument (off-timeline) · Assessment: sound — the 2nd–3rd-century Sethian Gnostic corpus (the Three Steles of Seth, the Apocalypse of Adam, and the Holy Book of the Great Invisible Spirit / Coptic Gospel of the Egyptians) reworks the very same complex the pillars legend carries — Seth as progenitor of an elect race, a saving knowledge that survives the world's destruction by water and by fire, and a Seth-inscription hidden to be disclosed at the end. In the Three Steles the reworking is explicit and load-bearing: the two tablets of stone and brick on which Seth preserved his lore from flood and fire have become three inscribed steles, and the standard editor of the text ties them to Josephus's Antiquities by name. As a cognate / reception of the tradition the reading is sound; it reinforces the historicity page's finding with a fifth branch and shows the motif was live in Greco-Egyptian Gnosticism within a century of Josephus. The stronger claim — a direct textual dependence of the Sethian texts on Josephus — is not established and should not be asserted.

In the Three Steles of Seth… the traditional two steles, or tablets of stone and brick, on which Seth was said to have preserved from destruction by flood or fire the vast sum of astrological lore revealed to him (cf. Josephus Jewish Antiquities 1.67.1–71.5) have now become three steles recording doxological hymns.
— John D. Turner, introduction to The Three Steles of Seth, in Marvin Meyer (ed.), The Nag Hammadi Scriptures (HarperOne, 2007), p. 523. The claim of this page is that the Sethian-Gnostic literature — a body of 2nd–3rd-century texts built entirely around Seth as heavenly savior and progenitor of the elect "unshakable race" (γενεὰ ἀσάλευτος) — is a genuine cognate branch of the same antediluvian-knowledge-survival tradition Josephus reports, and that in one of its texts, the Three Steles, the pillars-of-Seth image proper has been directly transformed. It is the reception of the legend not sideways into Egyptian pyramid-lore (as with Surid) but upward, into a mythology where Seth's inscribed knowledge becomes the revealed hymnody of salvation.1
The link is drawn by the scholarship on the Sethian corpus itself. John D. Turner — who, developing Hans-Martin Schenke's grouping of "Sethian Gnosticism," is the standard authority on these texts — makes the connection to Josephus explicit in his introduction to the Three Steles, cited above; the tie attaches specifically to that text, not to the Apocalypse of Adam or the Gospel of the Egyptians. Birger A. Pearson, in the standard survey of the field, sets out the broader Seth-traditions on which these texts draw — the Jewish exaltation of Seth as the righteous ancestor of an elect line, inherited and radicalized by the Gnostics into Seth the divine progenitor of "another race" (ἀλλογενής, "the stranger"). The Charaxio hidden-book text was established by Alexander Böhlig and Frederik Wisse in the critical edition of the Gospel of the Egyptians.2
The Three Steles: a direct transformation of the two pillars. The Three Steles of Seth (NHC VII,5) is a set of three doxological hymns — to the Father (Autogenes), the Mother (Barbelo), and the pre-existent One — framed as revelations "written" by Seth and preserved for the elect "living and unshakable generation," and "supposedly discovered by Dositheos," the reputed founder of Samaritan Gnosticism. Turner's reading is that this is the Josephan pillars image reworked: the two tablets of stone and brick against fire and flood have become three inscribed steles, the astrological lore has become salvific hymnody, and the "recovered after the catastrophe" mechanism has become "disclosed by Dositheos to the elect." The skeleton — Seth inscribes saving knowledge; it is preserved for a chosen race; it is revealed later — is the pillars legend's own, and the number has merely stepped from two to three.3
The Apocalypse of Adam: the race of Seth survives water, then fire. The Apocalypse of Adam (NHC V,5) carries the tradition's deep structure without the pillars-image itself. The seed of Seth passes through successive world-destructions: first the Flood — "rain-showers of God the almighty will be poured forth, so that he might destroy all flesh from the earth" — from which Noah (here renamed after the Greek flood-hero Deucalion) is preserved in the ark; then a second destruction by fire, in which "fire and sulphur and asphalt will be cast upon those men," and the light-bringers Abrasax, Sablo, and Gamaliel "descend and bring those men out of the fire and the wrath, and take them above the aeons." The same doubled fire-and-water judgment the pillars legend is built to outlast is here the frame of salvation history — but the saving mechanism is the rescue of the people, not inscription on durable stone, so it supplies the thematic parallel, not a pillars-image.4
The Gospel of the Egyptians: Seth's hidden book, disclosed at the end. The Holy Book of the Great Invisible Spirit (NHC III,2 and IV,2) has the great Seth deposit "the book which the great Seth wrote" on "the mountain that is called 'Charaxio'… on which the sun has not risen," to remain hidden until it should "come forth… at the end of the times and the eras" and disclose "this incorruptible, holy race of the great savior." And the race passes, with Seth, "through the three parousias… the flood, and the conflagration, and the judgment of the archons and the powers and the authorities." Here are the two Sethian motifs the pillars legend fuses — a Seth-inscription hidden to be revealed later, and survival through flood and conflagration — standing side by side, though not welded into the single inscribed-pillar image.5
Taken together, the three texts show that within roughly a century of Josephus the entire complex — Seth, an elect race, saving knowledge, survival through water and fire, an inscription hidden and later revealed — was live and generative in Greco-Egyptian Gnosticism. That is exactly the kind of independent branching the historicity page reads across the Babylonian (Berossus), Egyptian (Manetho / the Hermetic Book of Sothis), and later Arab-Coptic (Surid) analogues: the pillars legend is one early node of a durable, cross-cultural motif, and the Sethian corpus is its Gnostic node.
What holds. The cognate / reception reading is well-founded. The Sethian corpus is not a vague thematic rhyme but a whole literature organized around the same Seth-and-saving-knowledge complex, and in the Three Steles the connection is as concrete as such things get: a specialist editor identifies the three inscribed steles as a transformation of the very two stone-and-brick tablets Josephus reports, and cites the Antiquities passage to make the point. The water-then-fire survival pattern in the Apocalypse of Adam and the hidden-book-revealed-at-the-end motif in the Gospel of the Egyptians corroborate that the tradition's building-blocks were all in Sethian hands. As a datapoint it is valuable: it dates a live reception of the motif to the 2nd–3rd century, in Greek and Coptic, among readers who had made Seth the center of a salvation myth — a genuinely independent branch alongside the Babylonian, Egyptian, and Arab-Coptic ones.
What is overstated or unproven. Three cautions hold the finding to its scope. (a) Direct dependence. That the Three Steles transforms the two-pillars image does not establish that its author read Josephus. Turner's "cf. Josephus" marks a shared tradition, not a source-citation; the two-tablets-against-fire-and-flood motif was common Jewish property (told of Seth in the Life of Adam and Eve and of Enoch in the Palaea Historica), and the Sethian author most plausibly drew on that stream, not on the Antiquities specifically. So "the Steles copy Josephus" is a conjecture, not a finding — the same distinction the Surid page draws between cognate and copy. (b) The pillars-image is only in the Steles. Of the three texts only the Three Steles carries the inscribed-stele mechanism; the Apocalypse of Adam saves its elect by rescue, and the Gospel of the Egyptians keeps hidden-book and fire/flood-survival as two distinct motifs. The corpus supplies the complex the legend belongs to; it does not multiply the pillars-image itself. (c) Direction of the transformation. The Sethian texts invert the legend's point as much as they inherit it: where Josephus's Sethites discover astronomy by their own virtue, the Gnostic Seth reveals a saving gnosis from above, and celestial lore is more often the archons' snare than a prize to be preserved. The Sethian corpus is a reworking that carries the frame while remaking its content — a reception, not a transmission.6
Sound as a cognate / reception claim; conjectural as a direct-dependence claim. Keep the two apart. That the 2nd–3rd-century Sethian-Gnostic corpus reworks the same Seth + elect-race + saving-knowledge + water-and-fire-survival complex the pillars legend carries is well-supported: the Apocalypse of Adam runs the seed of Seth through destruction by water (Noah/Deucalion) and then by fire, sulphur, and asphalt; the Gospel of the Egyptians has Seth hide his written book on Mount Charaxio to be disclosed at the end of the ages, the race passing through "the flood, and the conflagration, and the judgment"; and the Three Steles of Seth is a direct Gnostic transformation of the two stone-and-brick pillars into three inscribed steles — a link its standard editor, John D. Turner, makes to Josephus's Antiquities by name. On that level it is a fifth independent branch of the motif, and its earliest, showing the tradition alive in Greco-Egyptian Gnosticism within a century of Josephus — a reinforcement of the historicity finding, not a rival to it. What does not follow is a direct textual dependence on Josephus: the shared two-tablets motif was common Jewish property, the inscribed-stele image proper appears only in the Three Steles, and the Sethian reworking inverts the legend's point even as it keeps its frame. So affirm the cognate; treat "the Sethian texts derive from Josephus" as an unproven conjecture; and read the corpus as a Gnostic reception of one durable antediluvian-knowledge tradition.
