The Pax Romana is often known as a 200-year period of peace, stability and prosperity. It lasted from 27 B.C.E. until about 180 C.E. It was a time of great discoveries in science, technology, engineering, and literature.
Ptolemy was a Greek writer, known as a mathematician, astronomer and geographer. He was the scientist who came up with the theory that the Earth is the center of the universe.
Galen was a Greek who became the Roman Empire’s greatest physician. He consolidated the work of previous Greek medical researchers, adding the results of his own research, to create an incredibly long-lasting medical doctrine.
Aqueducts, Plumbing, Baths, Roads, Bridges, Harbors and Dams were all technologies invented in the Pax Romana period. This allowed for easier water transportation within the Empire.
The colosseum is located in the middle of the city. It was circular in shape with three levels of arches around the outside. In height, the Coliseum was as tall as a modern 12-story building; it held 50,000 spectators. Now with the colosseum, Romans have a place for entertainment and events.
Many of the advances in architecture and building relied upon the Romans' discovery of concrete. Concrete made possible the creation of huge rounded arches and domes. One of the most famous structures built during the Pax Romana, the Pantheon in Rome, has one of the largest freestanding domes in the world to this day.
The Pax Romana ended because the Roman state had ceased to grow. Boundaries had been set for the Empire, and for the first time the army had become a drain on the economy of Rome. After the death of Marcus Aurelius came a succession of poor leaders, and so began not only the end of the Pax Romana but the fall of the Roman Empire.
