That is extremely helpful, is it known which journal (?) those 'Notes' by J R Allen were taken from please?
I originally thought the larger cup marked stone 'A' (JRA p91) was the 'footprint' stone because there are overlapping cupmarks on one corner. But yes - as you say - his stone 'B' (JRA p92) has numerous double-circle impressions on it which must be what gave rise to the local impression of footprints?
So where in all this is the Monzie 'Witches Stone' I wonder - it must be the single standing stone 300 yards / metres NW of the circle, an un-cupmarked stone which is 5 feet tall? An outlier - an alignment?
Please don't trek over to Monzie on my account, that download find was quite helpful enough - many thanks!
A lot of Scottish RSCs have cup marks, I was amazed to read that the moon theory for the recumbent stones was never universally accepted, I thought it was a proven fact but it isn't, the true nature of these circles is still being debated according to Adam Welfare in his 'Great Crowns of Stone' (2011). Beautiful book btw, highly recommended.
