We are reviewing prehistory, mostly for Sass because she was so young when we did it four years ago for Spyder. On Sunday we read a couple of chapters and discussed art in particular, so I went searching for the famous prehistoric art at Lascaux.
Oh. My. Word.
The French Ministry of Culture has a fantastic website that is absolutely filled with information. It actually allows you a virtual walk through the cave itself, with detailed information on the individual paintings and engravings.
The site map gives the visitor direct links to information about the geology of the region, the discovery itself, the research on the artworks, and much more.
Even if your students aren't studying the era, the website is well worth a visit.
