Recently, scholars such as Terry Jones, formerly of the comedy group Monty Python's Flying Circus, have argued that the Romans were imperialists but not innovators. In architecture, this certainly cannot be true. Architects such as Severus and Kailer working for the emperor Nero, developed the concept of a rotating domed room. And even created flying buttresses long before they were reinvented in the middle ages to support the naves of gothic churches. One of the most remarkable buildings was erected during the reign of the Emperor Hadrian. And it was a temple to all the Gods, known as the Pantheon. One of the most remarkable temples in all of Rome is the Pantheon. And this was built by the Emperor Hadrian, who also seems to have been a pretty interesting architect. He was obsessed with circles, and squares, and spheres, and cubes, and putting all these things together into buildings. He loved the classical look, he liked the look of ancient Athens and temples. But he also liked things that were Baroque, that were very flashy, and which surprised, and astonished you. So, as you went into this building, which was surrounded by a magnificent portico, you'd be expecting to find the inside of a regular Greek temple. But instead when you get inside the building it has a Rotunda that just amazes you. And has an oculus to let in light, and make it fan all around the various niches that are inside this structure. So looking at it, its unique, and its probably the best preserve romans space from antique either we actually have surviving.
