The ancient Egyptian religious-cosmological tradition (c. 3100 BCE–Roman period) —
solar theology, the ordering principle of *maʿat* (truth/order/justice), a practical
decimal arithmetic and applied geometry (the *seked* slope, rope-stretching land
survey), and some of the most enduring sacred architecture ever built. Its
mathematics was genuinely capable but **practical and procedural**, not the occult
numerology later projected onto it by pyramidology and by Schwaller de Lubicz — a
projection this node is careful to quarantine.
Egyptian "sacred mathematics" lived in two registers: the **religious-cosmological** (maʿat as the order the king must uphold; the solar cycle; the *benben* / primeval mound echoed in pyramid and obelisk; the fourfold ordering of space) and the **practical** (the Rhind and Moscow papyri show unit-fraction arithmetic, the seked for pyramid slopes, area of a circle as ≈(8/9 d)²). The two met in monumental building, where orientation and proportion mattered — but the sources give no sign of a hidden mystical number-science.

Evidence
Label
Practical, procedural mathematics (Rhind Papyrus, the seked)
Body
The Rhind Mathematical Papyrus (c. 1550 BCE, copied from a Middle Kingdom original) shows unit-fraction arithmetic, the seked (run-per-rise slope used for pyramids), and a circle-area rule equivalent to (8/9 d)² — competent applied mathematics, expressed as worked procedures.

Maʿat as the genuine cosmic-order concept
Body
Maʿat — order, truth, balance, justice — is the authentically Egyptian principle of cosmic and social order the king exists to uphold; it is the tradition's own "cosmic order," distinct from imported Greek or modern esoteric frameworks.

QUARANTINE: Schwaller de Lubicz's "sacred science" & pyramidology
Body
The claim that Egyptian temples (esp. Luxor) and the pyramids encode a hidden esoteric "sacred science" of proportion, φ and cosmic measures. Citation (for the claim): R. A. Schwaller de Lubicz, *Le Temple de l'Homme* (1957) / *The Temple in Man*; and the broader pyramidology literature. Note: QUARANTINED. Schwaller's esotericism is influential in "sacred geometry" circles but is NOT accepted by Egyptology; it retro-fits modern mysticism onto a practical-mathematics culture. Record as a *modern esoteric interpretation*, flagged, never as ancient Egyptian doctrine. Pairs with the Giza node's Orion/π quarantines.
