Lunchtime might be the best time to visit – apparently the stones dance everyday at noon.* They’re also known as the 17 brothers. That’s some discrepancy (especially as they are also known as the nine maidens – they were turned to stone for dancing on the sabbath) – I suppose nine is a rather special number (three times three), and maybe seventeen, as a prime number, also has its weirdness.
(partly from Grinsell’s ‘folklore of prehistoric sites in Britain’)
*This is mentioned in Notes and Queries 61 from 1850.
