Water is the wellspring of all life, but in diluvial proportions, it also becomes a specter of death. The mythos of the Abrahamic religions and many others describe a great flood, and it’s not hard to see why the shock of such a calamity might lead to fervor. Just observe the vast destruction wrought a few weeks ago in Kerr County, Texas, where the Guadalupe River surged 28 feet in 90 minutes, inundating Camp Mystic and ultimately leading to 135 deaths.
