https://en.wikipedia.org/wiki/Newark_Holy_Stones
In one of my volunteer activities I help staff a small museum which has displays and artifacts about Ohio history. One of the amusing stories is about the Newark (Ohio) holy stones, 'discovered' in an excavation of an Indian mound in 1860, and believed by some at the time to be proof that the 10 Lost Tribes of Israel had come to Ohio and built the Indian earthworks in the Ohio Valley. Don't worry, it was a fraud, pulled off as a hoax by someone who no doubt had a big laugh. I had seen the pictures many times before over the last ten years, but for the first time I actually looked a little closer and noticed the tetragrammaton on one of the supposed 'artifacts'! LOL, there it is, plain as day!
