A similar wooden origin for the Doric column has been advocated by some, who point to the assertion of Pausanias that in the Doric Heraion at Olympia the original wooden columns had with one exception been replaced by stone columns as fast as they decayed. (See p. 62.) This, however, only proves that wooden columns were sometimes used in early buildings, not that the Doric column was derived from them. Others would derive it from the Egyptian columns of Beni Hassan (p. 12), which it certainly resembles. But they do not explain how the Greeks could have been familiar with the Beni Hassan column long before the opening of Egypt to them under Psammetichus; nor why, granting them some knowledge of Egyptian architecture, they should have passed over the splendors of Karnak and Luxor to copy these inconspicuous tombs perched high up on the cliffs of the Nile. It would seem that the Greeks invented this form independently, developing it in buildings which have perished; unless, indeed, they brought the idea with them from their primitive Aryan home in Asia. +THE IONIC ORDER+ was characterized by greater slenderness of proportion and elegance of detail than the Doric, and depended more on carving than on color for the decoration of its members (Fig. 28). It was adopted in the fifth century B.C. by the people of Attica, and used both for civic and religious buildings, sometimes alone and sometimes in conjunction with the Doric. The column was from eight to ten diameters in height, against four and one-third to seven for the Doric. It stood on a base which was usually composed of two tori (see p. 25 for definition) separated by a _scotia_ (a concave moulding of semicircular or semi-elliptical profile), and was sometimes provided also with a square flat base-block, the _plinth_. There was much variety in the proportions and details of these mouldings, which were often enriched by flutings or carved guilloches. The tall shaft bore twenty-four deep narrow flutings separated by narrow fillets. The capital was the most peculiar feature of the order. It consisted of a bead or _astragal_ and echinus, over which was a horizontal band ending on either side in a scroll or volute, the sides of which presented the aspect shown in Fig. 29. A thin moulded abacus was interposed between this member and the architrave. [Illustration: FIG. 28.--GREEK IONIC ORDER. (MILETUS.)] The Ionic capital was marked by two awkward features which all its richness could not conceal. One was the protrusion of the echinus beyond the face of the band above it, the other was the disparity between the side and front views of the capital, especially noticeable at the corners of a colonnade. To obviate this, various contrivances were tried, none wholly successful. Ordinarily the two adjacent exterior sides of the corner capital were treated alike, the scrolls at their meeting being bent out at an angle of 45°, while the two inner faces simply intersected, cutting each other in halves.
