Crepidoma

Greek foundation of a building. Platform, crepis, or crepido on which a Greek temple stood, normally of three tall steps, the topmost platform surface of which was termed stylobate.

In classical Greek architecture, a stylobate is the top step of the crepidoma, the stepped platform upon which colonnades of temple columns are placed. The platform was built on a leveling course that flattened out the ground immediately beneath the temple

Fluting in architecture consists of shallow grooves running along a surface. The term typically refers to the grooves running vertically on a column shaft or a pilaster, but need not necessarily be restricted to those two applications. If the hollowing out of material meets in a point, the point is called an arris.

The convex curve given to a column, spire, or similar upright member, in an attempt to correct the optical illusion of hollowness or weakness that would arise from normal tapering. Entasis is almost universal in Classical columns.

An entablature is the superstructure of moldings and bands which lies horizontally above columns, resting on their capitals. Entablatures are major elements of classical architecture, and are commonly divided into the architrave, the frieze, and the cornice.
