TO most passers-by it looks little more than a weathered boulder lying forlorn on the side of a farm lane in East Lothian.
The faint markings etched on its sides are barely distinguishable, and to the untrained eye look like nothing more than graffiti scratches.
So when land factor Francis Ogilvy decided to move the heavy stone near Haddington in order to widen the farm lane beside it, he barely thought twice.
What he had no way of knowing is that he was potentially vandalising an ancient and protected monument.
