Take a look at this photo, what do you see?
Now look again and you will make the two perfect V’s cut into the clay. 2000 years ago my predecessors dug this double line of ditches around a small civilian town 100 k’s to the east of the Rhine on the endge of what is now the German town of Waldgirmes.
The Roman town included a forum with stone foundations and a guilded statue of Augustus rather indicating they planned to stick around for a while.
There was a bit of tussle in the trees at a place called Teutoburg and the intentions were revised. Shame really, if the Romans had stuck around we might have been able to skip that whole two world wars stuff. Who can say.
Meanwhile, thats some nice spade work guys, take a break.
