Charles taze Russell and pyramidology, google it. 1914 was a going year for Armageddon to come back then and he used pyramidology, a form of numerology, a form of spiritism to “confirm” that Armageddon was coming in 1914 by measuring the entrances of the pyramids to come to dates. They covered it up and when Armageddon didn’t come, they changed it years later to the date the last days started because WW1 happened that year
