Perthshire, Scotland — 8 September 1767
Large luminous pyramid leaves damage in its wake
“We hear from Perthshire, that an uncommon phaenomenon was observed on the water of Isla, near Cupor Angus, preceded by a thick dark smoke, which soon dispelled, and discovered a large luminous body, like a house on fire, but presently after took a form something pyramidal, and rolled forwards with impetuosity till it came to the water of Erick, up which river it took its direction, with great rapidity, and disappeared a little above Blairgowrie. The effects were as extraordinary as the appearance. “In its passage, it carried a large cart many yards over a field of grass; a man riding along the high road was carried from his horse, and so stunned with the fall, as to remain senseless a considerable time. It destroyed one half of a house, and left the other behind, undermined and destroyed an arch of the new bridge building at Blairgowrie, immediately after which it disappeared.”
