1.Cosmology Maps: Five Systems Compared
3 minSide-by-side visual maps of the Apocryphon of John, the Valentinian Pleroma, On the Origin of the World, the Pistis Sophia cosmos, and the Ophite diagram — showing where they converge and where they genuinely differ.
This volume is the visual companion to the entire Library, and its governing principle must be stated at the outset: there is no single Gnostic cosmology. There are cosmologies — related, overlapping, genuinely different maps of the invisible world, drawn by different communities in different centuries. The great temptation of every previous attempt to chart Gnostic thought has been to harmonize these into one master diagram, and that temptation is exactly what this Atlas refuses. Each system is mapped on its own terms, and the maps are set side by side so the reader can see both the convergences and the real differences (evidence class P1 for each system; evidence class C for the comparison).
Five systems anchor this opening comparison. The Apocryphon of John gives the fullest Sethian map: the invisible Spirit, Barbelo and the unfolding of the divine world, the four luminaries, Sophia’s fall, and the emergence of Yaldabaoth with his seven and his powers. The Valentinian Pleroma gives a differently structured map: the Depth and Silence, the ordered pairs of aeons unfolding to the Thirty, the passion of Sophia, and the powers of Limit and Christ that restore order. These two are the tradition’s most developed cosmologies, and they do not match in detail even where they rhyme in structure.
On the Origin of the World supplies a third map, closely related to the Sethian but with its own emphases — the extended narrative of Sabaoth’s repentance and elevation, the elaborate account of the rulers’ world. The Pistis Sophia gives a fourth, later and more baroque: a multiplied cosmos of regions, aeons, and orders through which the fallen Sophia must be raised. The Ophite diagram, known only through the hostile description of Origen (and Celsus before him), gives a fifth — a concentric or vertical arrangement of spheres and rulers that we can reconstruct only partially and provisionally (evidence class H for the Ophite reconstruction, since we possess no Gnostic original).
Reading these five side by side, certain convergences stand out and can be asserted with confidence (evidence class P2): all posit an unknowable Source; all place a fullness of divine aeons above; all describe a rupture associated with Wisdom; all interpose a maker-ruler and subordinate powers between the fullness and the human; and all locate a seed of light within the human that grounds the possibility of return. This shared architecture is real and important. But the differences — how many aeons, in what order, with what names, by what mechanism the fall occurs — are equally real, and the Atlas draws them faithfully rather than averaging them away.
A word on how to read the maps in this book. Every diagram in this Atlas uses a consistent visual grammar, explained in each chapter: solid lines for relationships explicitly attested in a primary text; dashed lines for relationships inferred by scholars from the texts; dotted lines for genuinely speculative or reconstructed connections. Colors and shapes are keyed to the evidence classes used throughout the Library. This means the reader can always see, at a glance, how firm the ground is beneath any part of a map — where the tradition speaks plainly, where scholarship reconstructs, and where honest uncertainty remains. The maps are arguments made visible, and their uncertainty markers are part of the argument.
