Horned serpent

A U of Cincinnati group claims to have evidence of an extra-terrestrial airburst at Hopewell sites across the Ohio River Valley. They suspect a comet was involved. Their range is from 252AD through 383AD: Chinese astronomers recorded 69 comets during this period, and the "The Miami tell of a horned serpent that flew across the sky and dropped rocks onto the land before plummeting into the river" "The Ottawa talk of a day when the sun fell from the sky" They claim evidence of fires over about 10K square miles.

"A horned serpent" is an evocative description. A comet with two tails?

Clearly the comet didn't hit, but a chunk might have broken off after warming up by the Sun. Chelyabinsk--or maybe more the size of Tunguska...

Interesting. I'd be surprised if there was just one chunk, though of course the odds of hitting the Earth are pretty small. Unless a small chunk blew up near someplace literate, we'd not know likely learn about it, and certainly have no idea about the date.

According to the Ohio History Central, the Ohio Hopewell built mounds up until 500AD, so they may have been set back by crop loss (as the article suggests), but they weren't done for. Assuming the platinum and iridium are the smoking guns here that they usually are...

Most serpent stories seem not to be astronomical, some do.

For the curious, W Bruce Masse proposes that the flood myths from around the world suggest that "only a globally catastrophic deep-water oceanic comet impact could account for all environmental information encoded in the corpus of worldwide flood myths" Hmm. Global tsunamis? Some places would be far less effected than others.
