Some folks suggest that there's pre-Stone Age, before we'd learnt how to shape flint into knives; Stone Age, when we could do that, and throw rocks at each other. Fire will have been tamed then.

The Iron Age came next, using charcoal and, later coal. The civilized discovery of the world. Our first literate king, gay King Edward II, is a part of it.

That's five, not four; but they seem useful.
