In ancient Israel, the high priests wore a vest that had two stones on it called the Urim and Thummim. Whenever a question about God’s will was brought to the priest, he would ask God to give the answer. If the stone on the left glowed, it indicated divine approval. If the stone on the right glowed instead, it indicated God’s disapproval.
On May 19th, 1780, a strange phenomenon turned a sunny morning into an unexpected night. The event, known as the Dark Day, was seen as a sign of divine judgment by contemporaries and as a means of ridiculing apocalyptic expectations by sceptics.
