Further insights into art and creativity in the past have recently been revealed at Stonehenge. Analysis of a laser scan of Stonehenge, commissioned by English Heritage, has discovered many more prehistoric rock carvings on the surface of the stones. It has also revealed that the surfaces of the stones were finished differently. Those stones on the north-east side of the monument have a finer surface finish, perhaps emphasising the importance of viewing the monument from this direction during the mid winter solstice.
More details can be found in the report.
A great example of the application of modern technology in helping understand creativity in the past.
