The Wandering Stone of Petty

Petty, Moray Firth, near Culloden, Scotland

The Seer foretold that a massive boundary stone, high and dry on the land, would one day be found far out in the sea with no one having seen it move — and in February 1799, an eight-tonne boulder vanished from its inland site and turned up 260 yards out in the water.

Among the boundary markers of Ross-shire and Moray stood the Stone of Petty, a boulder said to weigh around eight tonnes, planted firmly inland and marking the line between the lands of Culloden and Moray. The Brahan Seer is recorded as prophesying its impossible relocation in detail: "That the day will come when the Stone of Petty, large though it is, and high and dry upon the land as it appears to people this day, will be suddenly found as far advanced into the sea as it now lies away from it inland, and no one will see it removed, or be able to account for its sudden and marvellous transportation." On the 20th of February, 1799, the stone was found gone from its long-standing position. It was located roughly 260 yards away, out in the waters of the Moray Firth — precisely as far into the sea as it had previously stood inland, matching the prophecy's odd, mirrored geometry. No one had witnessed its movement, no storm or flood sufficient to carry an eight-tonne boulder that distance was recorded, and no explanation was ever agreed on. Of the Seer's prophecies, this is one of the few concerning an event with a precise, dated, and still-unexplained occurrence at its centre — a large object, publicly documented, that simply was not where it had always been.
