The Parthenon is an ancient Greek temple dedicated to the goddess Athena Parthenos (Athena the Virgin), on the Acropolis in Athens. 2 Most Greek cities had an acropolis (meaning "high city" in Greek). The Greeks developed three architectural systems, called orders, each with their own distinctive proportions and detailing. The Greek orders are Doric, Ionic, and Corinthian.3 The Parthenon architecture is of the Doric order. It is the earliest and simplest of the Greek architectural orders. The Parthenon's columns give an impression of graceful solidity and power. It was built from 447 to 432 BC, under the leadership of Pericles. The Parthenon was a rectangle marble temple measuring about 102 by 230 feet. It had 17 columns along each of its sides and 8 columns on each end. 4 The distances between the columns of the Parthenon vary mathematically so that when viewed from a distance, the columns reflected optical distortions. For example, a column that was perfectly straight would look like it was leaning outward. In order to compensate for this distortion, the builders inclined the columns inward just slightly.
There were four types of sculptures featured in the Parthenon. They were the statue of Athena, the Ionic frieze, the Doric metopes, and the pediments. Except for the gold and ivory statue of Athena, all of the other sculptures were painted with bright colors. When the Greek temple builders placed a sloped roof over the entablature it left a triangular space at each end
