Scenes Hathor has no parts for yet (4) — the next things to make

A team dragging a massive stone on logs, sprinkling water along a jungle path, ca. 1000 BCE.

Close‑up of masons striking stone with heavy hammers, rhythmic sparks flying, water spray catching the light, revealing polished surfaces emerging from raw rock.
The camera lingers on the silent summit as a faint echo of a hammer strike fades, leaving mystery in the air.
