Hancock claims in Heaven's Mirror (1998) that ancient sites were deliberately placed at specific longitude intervals from Giza — Angkor at 72° east, Nazca at 108° west. The intervals are multiples of 36°, tied to the precessional cycle. This has been repeated for 27 years without anyone testing it. So I did.
508,000 archaeological sites. 10,000 Monte Carlo simulations. 6 tests.
The short version: it doesn't hold up.
Sites do cluster at those longitudes, but only because sites cluster on continents, and continents happen to sit at those longitudes. Giza isn't special as a reference point (hundreds of random longitudes work just as well). 36° isn't special as a spacing (any evenly spaced set of angles performs comparably). The "precise" placements aren't precise – Angkor is actually 72.733° from Giza, Nazca is 111.2° not 108°, and Persepolis is 18.8° which isn't close to any multiple of 36°.
The most damning result: if someone deliberately placed monuments on a grid, you'd expect monuments to cluster at grid points more than settlements. The opposite is true… settlements are more aligned (15.4%) than monuments (9.3%). And older sites should align better if the grid was ancient. The opposite is true again – the oldest sites (12,000-8,000 BP) show exactly chance levels of alignment.
For context: I'm the same researcher who tested the Great Circle alignment – a different claim, first proposed by Jim Alison around 2001, that Giza, Nazca, Easter Island and other sites fall near a single circle around the Earth. That one IS statistically significant -monuments cluster on it at 5× the expected rate across 8 databases, while settlements don't. Same methodology, same databases. One holds up, one doesn't.
I don't have a horse in this race. I test claims and report what the data says. The Great Circle is real. The longitude grid is not.
