A slight convex curve in the vertical outline of a pilaster or of the shaft of a column.
The intentional convex curve of the upper two-thirds of a column, introduced to counteract the optical illusion of concavity produced by straight columns.
The bending or bow of the column shaft that gives it a curved profile. The bow starts 1/3 of the way up the shaft and helps make the column more aesthetically pleasing to the eye. the lower third of the column shaft is cylindrical.
a slight convexity in the shaft of a column; compensates for the illusion of concavity that viewers experience when the sides are perfectly straight
The slight tapering of a column; swelling towards the base.
The very slight swelling on Classical columns, to correct the optical illusion of concavity resulting if the sides are straight.
The portion of a classical column, which has a diminishing arc on the shaft. The lower third of the column is straight (two-thirds entasis column).
the convex swell found on classical columns, may be the full height of the column or the upper two thirds.
From a Greek word meaning, "to stretch." A slight swelling at the middle of a column designed to eliminate the optical illusion of hollowness which appears in a perfectly straight column.
Intentional slight convex curving of the side profiles in a tapered column to over come the optical illusion of concavity that characterizes straight-sided columns.
The curved profile of a column.
The slight convex curve used on Greek columns. This curve compensates for the optical illusion that a straight column seems concave.
The slight, convex swelling in the shaft of a column to prevent the illusion of concavity that would appear if the shaft was perfectly straight. Slight curing of a column toward its center.
Slight swelling of a column at the middle designed to overcome the optical illusion of hollowness that appears in a perfecting straight column.
the slight swelling at the center built into a Greek column
In architecture, entasis is a design technique used to counteract a certain optical illusion. When a column or other structure is designed with parallel sides, the sides appear to have a slight inward curve. Entasis is the inclusion of a slight outward curve in the sides - making them not parallel - to counteract this optical effect.
