Thunderstone (folklore)

Common card · No. 364999

A thunderstone is a prehistoric hand axe, stone tool, or fossil which was later used as an amulet to protect a person or a building. The name derives from the ancient belief that the object was found at a place where lightning had struck. They were also called ceraunia (a Latin word, derived from the Greek word κεραυνός, both of which mean 'thunderbolt').
