Platform and columns

A temple in Segesta is a good example to study the process of the construction, since it was abandoned in unfinished condition. Most Greek temples have three steps. Of course the base was layed at first, but upper step called stylobates was only arrenged at its outer frame, where the columns were settled. Outer surface of each stones were not smoothed and still had knobs to heave.

Although it is believed that some kind of crane was used, the shape and construction is unclear. However, the technique used for the mast probably made a contribution to it.

Then the columns were arranged. Each drums were also unfinished and still had knobs, however, since the lowest drum was difficult to flute when it was settled, lower part of the drum had been finished.

The upper and lower surface of the drum was not in same condition, but it was divided in four parts consist of concentric circles. Outermost surface was carefully smoothed to fit each drums. Its inner part was same level but the surface was rough to gain the rub. Next part was lower than other parts and the surface was coarse. Innermost part was same condition as outermost part.

Each drums had a rectangular hole on either side to insert a plug. It was maybe used as a guide to pile the drums accurately, rather than to fix them.
