How people used to travel the world

that ever was seen
And in sooth this is a thing done on the greatest scale of magnificence
that ever was seen. Never had emperor, king, or lord, such wealth as this
manifests! For it is a fact that on all these posts taken together there
are more than 300,000 horses kept up, specially for the use of the
messengers. And the great buildings that I have mentioned are more than
10,000 in number, all richly furnished, as I told you. The thing is on a
scale so wonderful and costly that it is hard to bring oneself to describe
it.[NOTE 4]
