Great Zimbabwe Site-Emblem T-Shirt

The Great Enclosure's curved dry-stone wall, built without mortar by ancestors of the Shona people, printed beside the geometry diagram Pyramason actually tested against claims linking the site to South Africa's Adam's Calendar, not an imagined network. Beneath it: Great Zimbabwe, Zimbabwe, -20.270936, 30.933198. Those are Pyramason's own catalogued coordinates for the largest pre-colonial stone complex in sub-Saharan Africa.

• Great Enclosure wall silhouette, built without mortar between 1100 and 1450 CE
• Geometry diagram shows the real Adam's Calendar corridor test: ratio 0.01, no invented network
• Exact coordinates (-20.270936, 30.933198) printed beneath the monument and country
• Soft, pre-shrunk cotton in a minimalist gold-on-dark line-art treatment

Why this site. Great Zimbabwe is the site where colonial denial of African engineering was strongest, and the corrective is the strongest too: this monument gave the modern country its name. Our own geometry testing confirms there's no hidden network needed to make the achievement remarkable; the real, documented history already is.
