🧵The cosmogram crowd are at it again. Sigh. Cool new site, Aguada Fenix, is interpreted by Takeshi Inomata et al as a big cosmogram. The article is here: science.org/doi/10.1126/..., with a journalism article in LiveScience here: livescience.com/archaeology/.... What's wrong with that? 1/6
Landscape-wide cosmogram built by the early community of Aguada Fénix in southeastern Mesoamerica
The cosmogram of Aguada Fénix built over the landscape between 1050 and 700 BCE rivaled the extents of later Mesoamerican cities.
