When I first started touring ancient Mexican ruins, I was amazed at how decorative they were. Even going so far as to putting little pebbles into the cement holding the big stones of pyramids and other grand structures together. I know…naive. But for those who thought like I did, until someone told me different, those stones are there for a reason. I’ve manipulated the image above to highlight the pebbles. They are places there when ruins are being restored as markers to show which parts have been restored. There is, however, another way of telling the difference between what’s been restored and what hasn’t….sharp edges – someone has been at it. A pile of rubble, or a big lump of mud and grass – someone hasn’t.
