The answer's comets, now what's the question?
This collage shows known depictions of comets from around the world across at least two millennia.
I argue in Prehistory Decoded that much of ancient and modern myth and religion is inspired by comets and their destructive effects. So comet symbolism should be everywhere. But where is it?
Below is a collage of suggestions. Maybe some are right, and some are wrong. What do you think?
From top left we have; 'hand' paintings from Catalhoyuk (thanks Ron!), stone plaquette from Gobekli Tepe, Teshub sculpture from Aleppo museum, Jewish Menorah, Shiva statuette, carvings in the roof of a dolmen in the Golan Heights (thanks James!), belt buckle on Pillar 18 at Gobekli Tepe, 'axes' carved into Stonehenge (thanks Ron, again), Inanna symbol from Mesopotamia, Ubaid 'keyhole' building, Apis bull from Ancient Egypt, and menat counterpoise from Ancient Egypt.
