I am posting this link for myself, mostly.  I would post it happily for everyone.  But, naturally, modern scholars can’t seem to help themselves.  They have included one section on Roman debauchery.  This one section takes a rated G post and turns it into a rated R post.  So, thanks for that, modern scholarship.

That said, here are 40 maps that explain the Roman Empire.

And, then, of course, there is the one map that explains the final collapse of the Roman Empire, and the dawn of the Dark Ages.  This is the one map that everyone ignores.
