This lovely work of art is in the Newcastleton Forest very close to the border with England. I think it must be ones of the 7 Stanes of the eponymous cycle routes. You'll see that Jerusalem is carved onto the side facing England and Ald Lang Syn faces into Scotland. Both songs seem timeless and perhaps a little nostalgic - to do with human perception of time. Time famously only goes in one direction. They talk about the Arrow of Time. You can cross the border in either direction but time only goes forwards. Hence we can look back on Ald Lang Syn or on Ancient Time but we can't look forwards to know the future. You can look both ways through the hole in the monument but you can only look with certain knowledge in one direction for time. This means time is an odd quantity in Physics. Space (by which I mean direction) is symmetrical in a sense, but time isn't.
