Re: Column Orders- help needed *LINK*

>No small order... it is a very deep subject. But here's my take on it in as short a write-up as I can give it (and even though I'm supposed to be an architect, I still had to look it up):
Column orders are derived from classical architecture, and there are 5 orders: Tuscan, Doric, Ionic, Corinthian, and Composite. The height is based upon the diameter of the column - which is divided into 3 parts - the pedestal (made up of the plinth, dado, and cornice); the column itself (made up of the base, shaft, and capital); amd the entablature (made up of the architrave, frieze, and cornice).
In the following, "d" will stand for column diameter (at the base).
For Tuscan:
Pedestal is 2.5d
Column is 7d
Entablature is 1.75d
Doric:
Pedestal is 2.67d
column is 8d
entablature is 2d
Ionic:
Pedestal is 3d
Column is 9d
Entablature is 2.25d
Corinthian and Composite:
Pedestal is 3.33d
Column is 10d
Entablature is 2.5d
These figures were reached by ancient greek architects as the most visually satisfying, and are generally a result of a mathematical equation that used the golden section as its root. It can get pretty deep, though - for example, there are calculations that govern the width of a column, which should be very slightly barrel shaped... The reason for that is more aesthetical than anything, as a set of columns that are all the same diameter look top heavy, and ones that are tapered evenly from the bottom to the top tend to look "too light" towards the top. The barrel shape compensates for these qualities...
