Arithmetic
Quantity, zero, numerals, equality, addition, subtraction, multiplication, base ten, sharing, and fractions.

Can understanding be rebuilt from stone alone?
The Obelisk is an attempt to carve a sequence of visual lessons into a permanent monument. A first complete four-face prototype now moves from arithmetic through geometry and physics to chemistry without depending on shared language or powered technology.
01 Conceptual face / knowledge in dependency order
September 2026 · prototype one
Eighteen panels now form one dependency chain.
The blank monument has become a reviewable 3D model: 57 illustrated lesson rows distributed across four subject faces. Every later face is restricted to marks, quantities, and relationships introduced earlier.
Geometry
Cord measurement, direction, turns, polygons, symmetry, perimeter, area, right triangles, scale, circles, and volume.
Examine the face ↗Physics
Repeatable time, motion, balance, levers, ramps, friction, gravity, fluids, heat, light, sound, and controlled comparison.
Examine the face ↗Chemistry
Mixtures, separation, dissolving, phase change, material transformation, conservation, and a cautious particle model.

What the model proves
It proves that the curriculum can be drawn, ordered, checked, and fitted to the supplied monument. It does not yet prove that an unbriefed reader can recover the intended meanings. Reader testing and fabrication studies are the next gate.
The idea in plain language
Not an archive of facts.
A path back to understanding.
A future reader may share none of our words, symbols, units, machines, or customs. The Obelisk asks whether carefully ordered marks could still teach that reader how to reconstruct foundational ideas.
01
Perceive
See repetition, difference, grouping, and change.
02
Infer
Connect a durable mark to a repeatable relationship.
03
Reconstruct
Use earned symbols to derive the next idea.
Face one · interactive reconstruction
Begin with no shared symbols.
Move through a simplified version of the first experiment. Each step is permitted to rely only on what the previous step established.
Step 01 · establish quantity
Repetition comes before number.
A reader can distinguish one mark from two and two from three without knowing what any mark is called.
What can be inferred
More marks represent more of the same thing.
The intended sequence
From a single mark to a testable model of matter.
Quantity
Counting, zero, operations, and scale.
Prototype completeGeometry
Shape, proportion, proof, and spatial relation.
Prototype completeMeasurement
Reproducible units rooted in physical reference.
IntegratedPhysics
Motion, mass, force, energy, and observable cause.
Prototype completeChemistry
Matter, mixtures, transformation, and conservation.
Prototype completeRules of the object
Every lesson must survive the same test.
No language required
Words may annotate the research, but the final encoding cannot depend on fluency.
No powered technology
No electricity, playback, computation, compression, or proprietary tool can be assumed.
Durable matter only
The intended substrates are stone, metal, glass, and fired clay.
Symbols must be earned
A mark gains meaning through demonstrated pattern, not declaration.
Damage is expected
Redundancy must preserve meaning through erosion, loss, and misordering.
Failure belongs in the record
Ambiguous and unsuccessful encodings reveal where reconstruction breaks down.
The work as it exists now
Active, incomplete, and open about uncertainty.
Codex is the working record. The Obelisk is its central construction experiment. Drafts are tested, revised, and retained when their failures teach something useful.
