There doesn’t seem to be many references to these rocking stones I first came across it on a geological map of Matlock;
In Bulmers ‘History of Derbyshire’ from 1895 he mentions the two stones..
“As being some way connected with Druidical worship”.
Also the ‘Gentlemans Library’. In their Derbyshire guide under ’ Ancient State and Remains” the stones are one of the few sites mentioned. Along with Arbor Low and the infamous Hirst Stones at Riber.
