I don’t have Google Earth installed, but I can see where this would be a very creative addition to the study of classic literature. How does geography play out in Macbeth? When Macduff says “I’ll to Fife” where is that? Where exactly is Birnam Wood?
You get the idea. You have to dig a little bit for the Shakespeare, but I found a Macbeth in the 9-12 section.
Somebody with Google Earth download one of these and see what it’s about, if it’s just a map or something more animated.
