Ionic Base
No. 166. Ionic Base.
The Ionic base differs from the Doric in the introduction of a hollow or scotia moulding between the two torus mouldings. Æsthetically it may be considered more satisfactory in that the strong shadow obtained by the use of the scotia produces an effect of binding which adds to the impression of strength. The type is technically known as the Attic base.
The total width is one and a third diameter.
The height of half a diameter may be divided into three. One of these divisions will give the height of the plinth, one the large torus and the fillet above it, and the other the scotia and small torus with the fillets above and below. The fillets either side of the upper torus may be in the same vertical alignment.
No. 167. Corinthian Base.
The smallest diameter of the base, which will be in the hollow of the scotia, should exceed the diameter of the shaft, or an effect of weakness will be imparted.
As in the Doric base a curve of a quarter circle connects the shaft with the upper fillet.
