The PantheonThe Pantheon was initially commissioned by Marcus Agrippa during the reign of Augustus (27 BC - 14 AD), it was later rebuilt by the emperor Hadrian around 125. The Pantheon is one of the most influential architectural designs in 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 lintel and post style construction. , but it is actually a circular building. If you had approached the Pantheon when it was first built, you would have approached it through a colonnade that would have hidden the barrel-shaped shape of the main part of the building. When you look at the Pantheon from the front, you see the traditional architectural design of the time, for a large building, the pillars and the pediment. The pillars are made of unique pieces of Doric-style marble, imported from Egypt. The pillars rise from the ground and merge with the pediment with its complex Corinthian capitals. The Doric style presents itself again in the frieze because it is simple and contains only one Latin phrase. The true grandeur of the building lies in the main room, the atrium is a huge open radial style space with a focal point being in the center of the room. The piece is filled with a combination of circles and squares that illustrates the Roman fascination with geometric shapes. Along with geometric shapes, the interior of this building is full of brilliant shades of oranges, blues and purples. There are Ionic-style pillars around the base of the room as well as sculptures of different gods. Just above the main room is a frieze of false windows which form a band around the middle level of the room. Although the windows are fake, there are big differences inside these buildings, over the past almost five hundred years the Romans have learned an enormous amount. As mentioned earlier, the Romans mastered the use of concrete, which allowed them to construct stronger and larger 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, pillars, pediment and frieze, although they share these elements they are very different from one building to another. The Pantheon shows how, through advances in technology, bigger and stronger things can be built. The Greeks, however, demonstrate great expertise in the Parthenon, with its sculptures and reliefs. The fact that these buildings still stand today is a testament to the genius of the Romans and Greeks.
