I run Boyne Valley Tours and noticed how often sheep are in photos of megalithic sites :
Newgrange, Tara, Loughcrew,
Avebury and more.
Looks a bit like a sheep too, texture and colour
This is such a beautiful stone - I visited Boscowen-un stone circle in Cornwall earlier in the year which has just one white quartz stone, not as beautiful as this one though. tjj
