Grim Reaper originated during the Black Plague: A hooded alien standing @ a Crop Circle field Whisking germs.

Same paranormal type hooded figure gave Thomas Jefferson the idea for the US money too. Same as the Russian mystic -- Nicholas Roerich that was mentor to the vice president of FDR described, as well Aleister Crowley w/ LAM. the origins of the all seeing eye on the dollar bill came from these instructions.

Anyway, crop circles and hooded aliens were described in medieval art and literature. Some, like some old French letter, described scaly ones coming out of the sea and then everyone got ill and died.

several accounts in different eras describing same thing. Recent account is in Russia and scientists studying the underground SUNKEN CAULDRONS. Every time scientists go there they fall ill.
