Another comment of the highest quality, it is worth writing these articles for that if for nothing else. The Sumerians is a topic have a lot of text books regards, and will do a series of posts on them alone, it will have to be a week long series at some point in time, due to the sheer number of amazing things they wrote, built and how they shaped and moulded the world around us, stick with me my friend, as we go deeper and further back in mystery and time. Have a superb week. Tips hat, offers a beer and gets back to writing.
