Answer:
The Parthenon is thought of as the most perfect Doric temple ever built. There are subtle refinements though that deviate from absolute regularity such as the curvature of the stylobate, and the Doric Order of the columns which creates a slight bulge in them.
Step-by-step explanation:

The purpose of the columns was to support the weight of the ceiling. Each order of classical architecture used columns for this purpose, but the columns were differently designed. In the Doric Order, the column shaft is simple and tapered, meaning it is wider at the base than the top.
