In the arid Karoo region of South Africa, researchers have discovered a series of subterranean caches containing thousands of ostrich eggshell fragments etched with celestial maps. These 6,000-year-old artifacts were found arranged in circular patterns around central hearths, pointing to the existence of prehistoric 'Star-Tracking Festivals' among early hunter-gatherer societies.
The fragments show evidence of being stained with rare blue pigments derived from local minerals, a color rarely seen in the region's rock art. Analysis suggests these gatherings occurred during the heliacal rising of specific constellations, marking a seasonal transition that was celebrated with communal storytelling and the ritual breaking of the shells to 'release' the spirits of the stars back into the sky.
