The Gothic mouldings in receding planes disappear entirely, and the classic architrave takes their place. The orders are again revived and are used (as the Romans often used them) as purely decorative features added for the mere sake of ornament to a wall sufficient without them, and are freely piled one upon the other. Palladio (a very influential Italian architect) reproduced the use of lofty pilasters running through two or even more storeys of the building, and often combined one tall order and two short ones in his treatment of the same part of the building, a contrivance which in less clever hands than his has given rise to the greatest confusion.

The Renaissance architects also revived the late Roman manner of employing the column and entablature. They frequently carried on the top of a column a little square pier divided up as the architrave and frieze proper to the column would be divided, and they surmounted it with a cornice which was carried quite round this pier, and from this curious compound pedestal an arch will frequently spring. The classic portico, with pediments, was constantly employed by them; and small pediments over window heads were common. A peculiarity worth mention is the introduction in many Italian palaces of a great crowning cornice, proportioned not to the size of the columns and of the order upon which it rests (if an order be employed), but to the height of the whole building. Much fine effect is obtained by means of this feature; it is, however, better fitted for sunny Italy than for gloomy England, and it is not an unmixed success when repeated in our climate.

Towers are less frequently employed than by the Gothic architects, and indeed in Italy the sky-line was less thought of at this period than it was in the middle ages. In churches, towers sometimes occur, nowhere more picturesque than those designed by Sir Christopher Wren for many of his London parish churches. The frequent use of the dome takes the place of the tower both in churches and secular buildings.

Openings.

Openings are both flat-headed and semicircular, occasionally elliptical, but hardly ever pointed. Renaissance buildings may be to some extent divided into those which depend for effect upon window openings, and those which depend chiefly upon architectural features such as cornices, pilasters, and orders. Among the buildings where fenestration (or the treatment of windows) is relied upon the palaces of Venice stand pre-eminent as compositions admirably designed for effect and very successful. In them the openings are massed near the centre of the façade, and strong piers are left near the angles, a simple expedient when once known, and one inherited from the Gothic palaces in that city, but giving remarkable individuality of character to this group of buildings.

In roofs, including vaults and domes, we meet with a divergence of practice between Italy and France. In Italy low-pitched roofs were the rule: the parapet alone often formed the sky-line, and the dome and pediment are usually the only telling features of the outline. France, on the other hand, revived a most picturesque feature of Gothic days, namely, the high-pitched roof, employing it in the shape commonly known as the Mansard[30] roof. Nothing adds more to the effectiveness of the great French Renaissance buildings than these lofty terminals.

The dome is, however, the glory of this style, as it had been of the Roman. It is the one feature by which revived and original classic architects retain a clear and defined advantage over Gothic architects, who, strange to say, all but abandoned the dome. The mouldings and other ornaments of the Renaissance are much the same as those of the Roman style, which the Italians revived; their sculptures and their mural decorations were all originally drawn from classic sources. These, however, attained very great excellence, and it is probable that such decorative paintings as Raphael and his scholars executed in Rome, at Genoa, at Mantua, and elsewhere, far surpass anything which the old Roman decorative artists ever executed.

Construction and Design.

The earlier Renaissance buildings are remarkable for the great use which their architects made of carpentry, as the most modern structures are for the use of wrought and cast-iron construction. As regards carpentry, it is of course true that all the woodwork of the classic periods, and much of that done in the Gothic period, has perished, either through decay or fire; but making every allowance for this, we must still recognise a very great increase in the employment of timber as an integral part of large structures. Vaulted roofs for example are comparatively rare, and domes, even when the inner dome is of brickwork or masonry, have their outer envelope of carpentry. A disuse of brick and rough masonry, or rather a constant effort to conceal them from view, is a distinctive mark of Renaissance work. The Roman method of facing rough walls with fine stone was resorted to in the best buildings. In humbler buildings plaster is employed.

Renaissance architects made very free use of plaster. Inside and out this material is utilised, not merely to cover surfaces, but to form architectural features. Cornices, panels, and enrichments of all kinds modelled in plaster are constantly employed in the interior of rooms and buildings. On the exterior we constantly find imitations of similar architectural features proper to stone executed in plaster and simulating stone; a short-sighted practice which cannot be commended, and which has only cheapness and convenience in its favour. There can be no question of the fact that the features thus executed never equal those done in stone in their effectiveness, and are far more liable to decay.
