Interestingly, other early monuments in the locality - such as Rothiemay recumbent stone circle - have been supposed to align with astronomical events and, consequently, evidence of early horology.

This is a later monument, but to my mind still an indication of "pre-historic science" - and just how advanced it could be.

As an aside, I was always pleasingly intrigued by the fact that Rothiemay was furthermore the birthplace of James Ferguson...
