Because the coastal area in Brittany, France has so many diverse megaliths, and since some are even said to date back about 6500 years, probably the oldest yet known, I suggest we look at some of the megaliths in this particular area. Here's an illustration of the relative size of one to a modern house:

Here's a menhir close to water. This tells us little about where the water was, whether lake, river or ocean, when this megalith was set up. It could have been close by or a mile or two away several thousand years ago:

Here's another menhir. This one seems to have been finished, or 'dressed' more than the other two we just saw:

Here's a much smaller standing stone, not really qualifying as a megalith. It seems to have a curious resemblance to a human figure in profile:

Here are some megaliths of varying sizes, apparently originally set up in rows. Probably some have been broken up and taken away for more modern purposes. This seems to have happened in many locations around the world:

Here's a dolmen at Carnac, showing its entrance:

And here it is from the inside, looking out:

Having seen some examples of what are said to be more than ten thousand megaliths in the Carnac area, in Brittany, France, we are now ready to consider what was motivating the Stone Civilization as I have called it. I would further suggest that what we have seen and discussed so far is merely on the outskirts or perimeter of this civilization, and we have yet to consider what was probably its centre. This we'll do in the next chapter.
