Lightning-prints are appearances sometimes found on the skin of men or animals that are struck by lightning, and are currently believed to be photographic representations of surrounding objects of scenery.

At Candelaria, in Cuba, in 1828, a young man was struck dead by lightning near a house, on one of the windows of which was nailed a horse-shoe; and the image of the horse-shoe was said to be distinctly printed upon the neck of the young man. On the 14th of November, 1830, lightning struck the Chateau Benatoniére, in Lavendée. At the time a lady happened to be seated on a chair in the salon, and on the back of her dress were printed minutely the ornaments on the back of the chair. In September, 1857, a peasant-girl, while herding a cow in the department of Seine-et-Marne, was overtaken by a thunder-storm. She took refuge under a tree, and the tree, the cow and herself were struck with lightning. The cow was killed, but she recovered, and on loosening her dress for the sake of respiring freely, she saw a picture of the cow upon her breast.
