Describe two of the three column styles found in ancient greek architecture.

Ionic, Doric, Corinthian. 

Well, the three column styles is Ionic, Doric and Corinthian. Depending of which one you choose, you need to know the differences between them.

Explanation:

Each column style belongs to a period of Greek History, and it represents the evolution of Greek art. By this way, we have:

Doric style is the simplest one, and has no base. The Ionic columns usually had statues of gods or heroes on top. The Doric order is the oldest, supposedly defined in its main characteristics between 600 and 550 BC, the time of the earliest known remains of Greek temples.Ionic columns are taller than Doric columns and their surface has carved lines from top to bottom. The base of an Ionic column looks like a pile of rings, and the capital at the top of the column appears to be a giant scroll. After the Doric order, the Ionic order developed from the 5th century BC.Corinthian is an evolution of the Ionian order towards a greater appreciation of ornamentation, a striking trend between the late 5th century and the early 4th century BC. The most striking difference from the Corinthian to the Ionian order is the much more elaborate column capital. It had the basic shape of an inverted bell, adorned with leaves and buds of acanthus, a local plant. Another difference, though not so striking, was the height of the columns, which was eleven times the diameter, while the Ionic columns were nine times the diameter.
