A reader of the blog has sent me two images of a puzzling object they recently found along the Boyne estuary. It consists of a roughly oval, flat stone that has a pattern carved into one side (the mobile phone in the image above gives a sense of scale).
The carving consists of a centrally placed raised lip/bar running widthways across the stone and then six diamonds running lengthways, which appear to be in a recessed channel. The overall effect being slightly cruciform.
The opposite side of the stone has another raised bar/lip along which is inscribed ‘Gibson buckle’ or possibly ‘Qibson buckle’ . Any ideas what this mystery object may be?
