in decided parabolic curves, of which the departure from straight lines is greatest at about two-thirds of the height of the shaft. This curve of the shaft is called the _entasis_; and upon it depends mainly the expressional life of the shaft. It will be remembered that there is a similar swelling in the Egyptian shaft; but this is where it approaches the base. Its position in the Greek shaft expresses an ascendant energy of force, which is manifested most strongly as it approaches the capital. In the one case yielding under weight is expressed, in the other superabundant power. This animated expression is multiplied by every multiplication of the outline provided by the flutings, which in the Greek shaft are concave, expressing concentration of force towards the centre; whereas, in the Egyptian the flutings are convex, expressing further a tendency to bulge and burst under their burthen. A little under the capital, and just where the Greek shaft is thinnest, one or more deep channels are incised in its substance, showing that power can be triumphantly cast away just where power is most needed. The Egyptian shaft, at the same point, is usually bound with a heavy thonglike moulding, as if to prevent it from being crushed. The ovolo, which constitutes the Doric capital, provides and expresses the distribution of the power of the shaft to meet the superincumbent entablature; and the “quirk” or sudden diminution of its breadth immediately under the abacus is a repetition of the device of the incised channels for proving the existence of superabundant power. At the point where the Greek entablature is met with easy grace by the noble spread of the hyperbolic ovolo, the Egyptian capital, as a rule, diminishes and seems to dash itself with violence towards the point of conflict.
