You could learn how to get an education and if you did you could move up that system and you could marry into other systems. And interestingly enough, women were considered to be equal of men in Egyptian life. Not only could they own property and could they trade and be merchants, but they could also demand a divorce. And in the divorce they were entitled to part of the property that was shared with their spouse. So that's going to go away for a very long time, but it shows you that in ancient civilizations they didn't exactly see men and women as we're going to see them develop in Europe and in Western civilization until really we get until the 20th century. Now there's also of course other really important aspects of Egyptian life that we should mention. Of course they have been to Mesopotamia, they've been to the mountaintop, there's not really a mountaintop there, but they do come back with the idea of writing, of cuneiform.
