““the Doric order the column has no separate base, but rises direct from the top step of the platform on which the building it belongs to stands. It is of massive form and has what is known as an entasis or slightly convex surface, it is generally fluted, that is to say, cut into parallel perpendicular channels, several rings called annulets connecting it with the capital, which consists of an echinus or rounded moulding and an abacus or unrounded slab resting on the echinus. The Doric entablature is equally simple, the architrave being perfectly plain, whilst the frieze is adorned with triglyphs or three upright projections with grooves between them, set at equal distances from each other, the spaces separating them, known as metopes, being as a rule enriched with fine sculptures of figure subjects. The frieze is connected with the cornice by narrow bands called mutules resting on the triglyphs and metopes, and the cornice itself has a plain lower band known as the corona, surmounted by more or less decorated courses of stone or marble. The Ionic and Corinthian orders are alike characterised by lightness and grace rather than massiveness and simplicity. In both, the columns, instead of rising direct from the platform, have a complex base consisting of a number of circular mouldings above another, the fluted shafts are comparatively slim and tapering, and the channels in them are divided by spaces called fillets. In the Ionic order the flat abacus of the Doric capital is replaced by two coiled volutes projecting beyond the echinus on either side, and the horizontal portion between the volutes is surmounted by finely carved leaf mouldings. The Corinthian order is specially distinguished by the ornate decoration of the capitals, that represent calices of flowers and leaves, chiefly those of the acanthus, arranged so as to point upwards and curve outwards in much the same style as they do in nature. The architrave in both the Ionic and the Corinthian orders consists of plain slabs, but the frieze—which is not divided as in Doric buildings into triglyphs and metopes—is in nearly every case enriched with a series of beautiful figure””
