SESHAT'S NORTHERN ANCHOR HYPOTHESIS - Phecda–Megrez, Meskhetyu, and the Inherited Origin of Egyptian Sacred Orientation

Destination II established the interior of the Great Pyramid as a vertical cosmological sequence. It did not address how the monument was placed on the ground. That question has an unresolved literature of its own: Old Kingdom builders oriented their pyramids to true north within a few arcminutes, and after twenty-five years of archaeoastronomy seven incompatible proposals stand in the field, no two of which can both be complete accounts. This paper tests one of them computationally and then argues, as a separate claim, that the technique it implies was inherited rather than invented in the Fourth Dynasty. The proposal tested is Belmonte's: the simultaneous vertical transit of Phecda and Megrez, both of which lie inside Meskhetyu, the Foreleg of the Bull — the one constellation the Egyptian foundation texts actually name. Of the twenty-one possible pairs within that asterism, a deposited script finds that exactly one reaches true north in the relevant era, at 2553 BCE, an epoch Irina Tupikova independently recomputes. The paper does not let that stand as a result on its own. A control enumerating all 31,824 seven-star subsets of the naked-eye circumpolar set shows that one capable pair is the expected count for any seven circumpolar stars, and that Meskhetyu's margin over its next-best pair, while above median, is not exceptional. What carries weight is the epoch, and that is quantified too: chance supplies a coincidence of this kind between about two times in five and one in fifteen depending on which element is treated as random, a likelihood ratio of roughly 2:1 to 15:1 — moderate evidence from a test that could have failed, and not decisive. Of the pair's two daily alignments, only the upper matches Khufu's measured deviation in direction as well as in size, which places the orientation at about 2567–2557 BCE, some two decades into this series' long reign for Khufu rather than at his accession. Applied to every dated pyramid, with Belmonte's own assignment of each monument to the upper or lower alignment, the same pair places Meidum through Neferirkare in historical order within the builders' precision and without measurable drift, so the reversal of rotational sense at Menkaure becomes what continued use of one method predicts rather than an anomaly needing explanation. The single monument it cannot place is Djedefre's, built away from Giza by the first king titled Son of Ra. What selects the pair is stated as a dependency rather than a finding. Dropping the constraint that both stars lie inside the named constellation, nine pairs reach true north in the same window, eight of them using stars outside Meskhetyu; and the rival pairings of Spence and Tupikova fit the dated sequence better or worse according to which survey of Menkaure's pyramid is used. The geometry does not single out Phecda–Megrez. The text does. The inheritance argument rests on the foundation ceremony pedj-shes, patronised by Seshat and attested from the First Dynasty on the Palermo Stone, depicted from the Second, and recorded in full at Edfu, where the king says he turns his sight according to the movement of the stars and allows his eyes to enter into Meskhetyu; on Old Kingdom evidence independent of that ceremony in which one word and one sign serve both the asterism and the adze of the Opening of the Mouth; on Dendera, whose cord-stretching temple is itself oriented to the rising of Meskhetyu; and, before the dynasties, on Nabta Playa, where megaliths and burials show orientation actively rebuilt to account for precession. The paper names its own weakest joint: the Meskhetyu attribution of the Predynastic structure HK29A at Hierakonpolis rests on a single source, and the conditions an independent re-measurement would have to meet to count as support are stated in advance. The load-bearing inheritance claim is not free-standing either — it depends on the corridor migration and genetic continuity established in Corridor I–III, which are cited rather than re-argued. Seven falsifiable predictions are reported with their current status, and one is now supported: re-run from van Leeuwen's independent re-reduction of the raw Hipparcos observations, Phecda–Megrez reaches true north at 2552 BCE and remains the only capable pair within the asterism, with its margin intact. The catalogue the prediction originally named cannot perform the test, and that failure is deposited as a reproducible query result rather than asserted. Every figure quoted in the paper is recomputed by the deposited script. This is a supplementary hypothesis to Destination II of the Zep Tepi Series.
