Although I seem to be on a roll with linking to ScienceNews stories, this is too amazing to pass up: “People living at least 2,000 years ago near the Pacific Coast of what’s now Guatemala crafted massive human sculptures with magnetized foreheads, cheeks and navels. New research provides the first detailed look at how these sculpted body parts were intentionally placed within magnetic fields on large rocks.”
The magnetic fields were likely created by lightning strikes.
This is incredible: “Artisans may have held naturally magnetized mineral chunks near iron-rich, basalt boulders to find areas in the rock where magnetic forces pushed back, the scientists say in the June Journal of Archaeological Science. Predesignated parts of potbelly figures—which can stand more than 2 meters tall and weigh 10,000 kilograms or more—were then carved at those spots.”
It’s like a geological farm for the secondary effects of lightning. A lightning farm for real!
The mind boggles at the thought of magnetic landscape architecture, or magnetic masonry in ancient stonework, or even huge sculptures invisibly adhering to one another through magnetic forces, giving the appearance of magic.
Imagine a valley of exposed bedrock and boulders, its unusually high iron content making the rocks there attractive to lightning. Over tens of thousands of lightning strikes, the valley becomes partially magnetized, resulting in bizarre geological anomalies mistaken for the actions of a spirit world: small pebbles roll uphill, for example, or larger rocks inexplicably clump together in structurally precarious agglomerations. Stones perhaps hover an inch or two off the ground, pulled upward toward magnetic overhangs, or rocks visibly assemble themselves into small cairns, clicking into place one atop the other.
As you step into the valley, the only sound you hear is a trembling in the gravel ahead, as if the rocks are jostling for position. Your jewelry begins to float, pulling away from your wrists and chest.
Anyway, read more at ScienceNews.
(Also, watch for my friend Eva Barbarossa’s book on magnets coming out this fall.)
