Doric Order.
The Doric was the order which the Greeks especially loved and cultivated so as to make it most exclusively their own; and, as used in the Parthenon, it certainly is as complete and as perfect an architectural feature as any style can boast of. When first introduced from Egypt, it, as before stated, partook of even more than Egyptian solidity, but by degrees became attenuated to the weak and lean form of the Roman order of the same name. Woodcuts No. [136], [137], [138] illustrate the three stages of progress from the oldest example at Corinth to the order as used in the time of Philip at Delos, the intermediate being the culminating point in the age of Pericles: the first is 4·47 diameters in height, the next 6·025, the last 7·015; and if the table were filled up with all the other examples, the gradual attenuation of the shaft would very nearly give the relative date of the example. This fact is in itself sufficient to refute the idea of the pillar being copied from a wooden post, as in that case it would have been slenderer at first, and would gradually have departed from the wooden form as the style advanced.[[137]] This is the case in all carpentry styles. With the Doric order the contrary takes place. The earlier the example the more unlike it is to any wooden original. As the masons advanced in skill and power over their stone material, it came more and more to resemble posts or pillars of wood. The fact appears to be that, either in Egypt or in early Greece, the pillar was originally a pier of brickwork, or of rubble masonry, supporting a wooden roof, of which the architraves, the triglyphs, and the various parts of the cornice, all bore traces down to the latest period.
Even as ordinarily represented, or as copied in this country, there is a degree of solidity combined with elegance in this order, and an exquisite proportion of the parts to one another and to the work they have to perform, that command the admiration of every person of taste; but, as used in Greece, its beauty was very much enhanced by a number of refinements whose existence was not suspected till lately, and even now cannot be detected but by the most practised eye.

The columns were at first assumed to be bounded by straight lines. It is now found that they have an entasis, or convex profile, in the Parthenon to the extent of 1⁄550 of the whole height, and are outlined by a very delicate hyperbolic curve; it is true this can hardly be detected by the eye in ordinary positions, but the want of it gives that rigidity and poverty to the column which is observable in modern examples.[[138]]
In like manner, the architrave in all temples was carried upwards so as to form a very flat arch, just sufficient to correct the optical delusion arising from the interference of the sloping lines of the pediment. This, I believe, was common to all temples, but in the Parthenon the curve was applied to the sides also, though from what motive it is not so easy to detect.
Another refinement was making all the columns slope slightly inwards, so as to give an idea of strength and support to the whole. Add to this, that all the curved lines used were either hyperbolas or parabolas. With one exception only, no circular line was employed, nor even an ellipse. Every part of the temple was also arranged with the most unbounded care and accuracy, and every detail of the masonry was carried out with a precision and beauty of execution which is almost unrivalled, and it may be added that the material of the whole was the purest and best white marble. All these delicate adjustments, this exquisite finish and attention to even the smallest details, are well bestowed on a design in itself simple, beautiful, and appropriate. They combine to render this order, as found in the best Greek temples, as nearly faultless as any work of art can possibly be, and such as we may dwell upon with the most unmixed and unvarying satisfaction.
The system of definite proportion which the Greeks employed in the design of their temples, was another cause of the effect they produce even on uneducated minds. It was not with them merely that the height was equal to the width, or the length about twice the breadth; but every part was proportioned to all those parts with which it was related, in some such ratio as 1 to 6, 2 to 7, 3 to 8, 4 to 9, or 5 to 10, &c. As the scheme advances these numbers become undesirably high. In this case they reverted to some such simple ratios as 4 to 5, 5 to 6, 6 to 7, and so on.
We do not yet quite understand the process of reasoning by which the Greeks arrived at the laws which guided their practice in this respect; but they evidently attached the utmost importance to it, and when the ratio was determined upon, they set it out with such accuracy, that even now the calculated and the measured dimensions seldom vary beyond such minute fractions as can only be expressed in hundredths of an inch.
Though the existence of such a system of ratios has long been suspected, it is only recently that any measurements of Greek temples have been made with sufficient accuracy to enable the matter to be properly investigated and their existence proved.[[139]]
The ratios are in some instances so recondite, and the correlation of the parts at first sight so apparently remote, that many would be inclined to believe they were more fanciful than real.[[140]] It would, however, be as reasonable in a person with no ear, or no musical education, to object to the enjoyment of a complicated concerted piece of music experienced by those differently situated, or to declare that the pain musicians feel from a false note was mere affectation. The eyes of the Greeks were as perfectly educated as our ears. They could appreciate harmonies which are lost in us, and were offended at false quantities which our duller senses fail to perceive. But in spite of ourselves, we do feel the beauty of these harmonic relations, though we hardly know why; and if educated to them, we might acquire what might almost be considered a new sense. But be this as it may, there can be no doubt but that a great deal of the beauty which all feel in contemplating the architectural productions of the Greeks, arises from causes such as these, which we are only now beginning to appreciate.

To understand, however, the Doric order, we must not regard it as a merely masonic form. Sculpture was always used, or intended to be used, with it. The Metopes between the triglyphs, the pediments of the porticoes, and the acroteria or pedestals on the roof, are all unmeaning and useless unless filled or surmounted with sculptured figures. Sculpture is, indeed, as essential a part of this order as the acanthus-leaves and ornaments of the cornice are to the capitals and entablature of the Corinthian order; and without it, or without its place being supplied by painting, we are merely looking at the dead skeleton, the mere framework of the order, without the flesh and blood that gave it life and purpose.
It is when all these parts are combined together, as in the portico of the Parthenon (Woodcut No. [139]), that we can understand this order in all its perfection; for though each part was beautiful in itself, their full value can be appreciated only as parts of a great whole.
Another essential part of the order, too often overlooked, is the colour, which was as integral a part of it as its form. Till very lately, it was denied that Greek temples were, or could be, painted: the unmistakable remains of colour, however, that have been discovered in almost all temples, and the greater knowledge of the value and use of it which now prevails, have altered public opinion very much on the matter, and most people now admit that some colour was used, though few are agreed as to the extent to which it was carried.
It cannot now be questioned that colour was used everywhere internally, and on every object. Externally too it is generally admitted that the sculpture was painted and relieved by strongly coloured backgrounds; the lacunaria, or recesses of the roof, were also certainly painted; and all the architectural mouldings, which at a later period were carved in relief, have been found to retain traces of their painted ornaments.
It is disputed whether the echinus or carved moulding of the capital was so ornamented. There seems little doubt but that it was; and that the walls of the cells were also coloured throughout and covered with paintings illustrative of the legends and attributes of the divinity to whom the temple was dedicated or of the purposes for which it was erected. The plane face of the architrave was probably left white, or merely ornamented with metal shields or inscriptions, and the shafts of the columns appear also to have been left plain, or merely slightly stained to tone down the crudeness of the white marble. Generally speaking, all those parts which from their form or position were in any degree protected from the rain or atmospheric influences seem to have been coloured; those particularly exposed, to have been left plain. To whatever extent, however, painting may have been carried, these coloured ornaments were as essential a part of the Doric order as the carved ornaments were of the Corinthian, and made it, when perfect, a richer and more ornamental, as it was a more solid and stable, order than the latter. The colour nowhere interfered with the beauty of its forms, but gave it that richness and amount of ornamentation which is indispensable in all except the most colossal buildings, and a most valuable adjunct even to them.
