This paper synthesises evidence from Thuban's equinoctial meridian altitude, the sexagesimal mathematical horizon of early Mesopotamia, and the geometry of a simple but powerful Neolithic theodolite-previously demonstrated in a patented reconstruction-to argue that the descending passage was engineered using a pre-dynastic astronomical instrument. The Lebanese cedar rod recovered by Waynman Dixon and described by Piazzi Smyth as a "measuring rod" is shown to be consistent with the sighting arm of such a device, complete with diagonal striations interpretable as an exponential scale. Radiocarbon dating of the rod (3341-3094 BC) aligns precisely with the epoch in which Thuban's altitude matches the passage's slope. The convergence of astronomy, engineering, and artefactual evidence suggests that the Great Pyramid monumentalised an earlier equinoctial-polar sightline established centuries before Khufu. ...
