While checking references for the Niaux Caves this week, I discovered this delightful website. It makes ancient history interesting, mysterious and real. It provides a lot of information on rock art and it's origins and culture. The iLecture films are inexpensive but well-done. I felt that the photographers could have visited Niaux on the day that I went.
