entasis (ĕn`təsĭs) [Gr.,=stretching], the slight convex curvature of a classical columncolumn,
vertical architectural support, circular or polygonal in plan. A column is generally at least four or five times as high as its diameter or width; stubbier freestanding masses of masonry are usually called piers or pillars, particularly those with a rectangular plan.

This device, as used by Greek builders, was of extreme subtlety, the freehand curvature being merely sufficient to guard the contours of the column from any appearance of inward sagging. In the Doric columns of the Parthenon, 34 ft (10.3 m) high and 6 ft 3 in. (1.9 m) in diameter at the bottom, the total convexity amounts to only 3-4 in. (1.91 cm). In Greek Doric columns the entasis began at the foot, but in the Roman orders it was confined to the upper two thirds of the column.EntasisIntentional slight curvature given to the vertical profile of a tapered column to correct the optical illusion that it appears thinner in the middle if the sides are left straight.Entasis in architecture, a convexity in the shaft of a column, usually located in the lower third of the column. It lends the impression of strength to the column and eliminates the optical illusion of concavity. entasis[′en·tə·səs] (architecture) The slight swelling visible in the profile of a column, used to correct the visual distortion that makes a straight column seem to have a concave profile. entasis  entasis: proportions are much exaggerated The intentional slight convex curving of the vertical profile of a tapered column; used to overcome the optical illusion of concavity that characterizes straightsided columns.entasisenUK
