The PantheonThe Pantheon was originally commissioned by Marcus Agrippa during the reign of Augustus (27 BC - 14 AD) and was later rebuilt by Emperor Hadrian around 125. The Pantheon is one of the most influential architectural designs of history, its pediment, pillars and dome are the most copied elements and their influence can be seen in construction around the world. From the front the building appears to be a post-and-lintel style construction, but is actually a circular building. If you had approached the Pantheon when it was originally built you would have approached through a colonnade which would have hidden the barrel shape of the main part of the building. Looking at the Pantheon from the front you see the traditional architectural design of the time, for a large building, pillars and pediment. The pillars are made of individual pieces of Doric-style marble, imported from Egypt. The pillars rise from the floor and merge with the pediment with intricate Corinthian capitals. The Doric style recurs in the frieze because it is sober and contains only one Latin phrase. The true grandeur of the building is in the main hall, the atrium is a vast open radial space with a central point located in the center frieze of the room. The room is filled with a combination of circles and squares that illustrates the Romans' fascination with geometric shapes. Along with the geometric shapes, the interior of this building is filled with bright shades of orange, blue, and purple. There are Ionic-style pillars around the base of the room and sculptures of several deities. Just above the main room is a frieze of false windows that forms a band around the middle level of the room. Even though the windows are fake, there are... half the paper... there are big differences inside these buildings, with a past of almost five hundred years the Romans have learned a lot. As mentioned above, the Romans mastered the use of concrete which allowed them to build stronger and grander buildings. Additionally, the Romans commanded a vast empire that allowed them to gather materials from distant lands. The Pantheon and the Parthenon are two of the most influential buildings in history. They share some basic styles, pilasters, pediment and frieze, although they share these elements they are very different in each building. The Pantheon shows how with the advancement of technology it is possible to build bigger and stronger things. The Greeks, on the other hand, show great mastery in the Parthenon, with its carvings and reliefs. The fact that these buildings are standing today is a testament to the genius of both the Romans and Greeks
