Walls and Civilization II

Hi,
From a comment about the US-Mexican Wall .

Good point .
A Wall always cuts both ways .
Cf Israeli wall , Berlin wall , Apartheid border walls ,Roman walls , etc .

Remember the effect of Hadrian's Frontier Walls on subsequent plagues ?
See http://andreswhy.blogspot.com "Hadrian and critical plague mass"

I am busy reading a very interesting book :
"The Empire stops here" by Philip Parker ISBN 9781845950033 .
R250 . Pp 649 Published 2010
A Journey along the frontiers of the Roman world .
To quote the blurb :
"A blend of travelogue , classical history and archaeology."

One should expand the travel to the Walls of the World .

A "Wow" itinerary .

Wishfully yours ,
Andre
