The following paragraphs are from an essay about the cursus publicus, the postal system of ancient Rome.
Paragraph 1
Established by Emperor Augustus, the cursus publicus was the state-sponsored transportation and postal system of the Roman Empire. Utilizing a vast network of paved roads, the system allowed the imperial government to send messages and officials rapidly across provinces. Relays of fresh horses and rest stations, known as mansiones, were positioned at regular intervals along main routes, ensuring that courier travel was highly efficient and secure.
Paragraph 2
[1] Indeed, access to this elite network was strictly limited to those carrying an official imperial pass, the diploma. Because the system was funded by heavy taxes levied on local provincial communities rather than the treasury, the Roman administration carefully guarded its use to prevent exhaustion of local resources. Unauthorized travelers who attempted to use the stations faced severe penalties.
