The mandala design that I created on the stone above was influenced by neolithic and celtic art. One of the most famous neolithic rock designs is the entrance stone located at Newgrange in Ireland.
The Entrance Stone was created about 5000 years ago in 3200 BC. Information about Newgrange can be found here… http://celtictours.blogspot.com/2011/06/explore-ancient-ireland-newgrange.htm
This is another version of my Celtic mandala design which was also created with the medium of painting with light.
