26. The temples of the Romans generally bore a strong resemblance to those of the Greeks, although they often differed from the specimens of that nation in several particulars. The stylobate of the latter was usually a succession of platforms, which likewise served the purposes of steps, by which the building was approached on all sides. Among the Romans, it was usually an elevated structure, like a continued pedestal, on three sides, and accessible in front by means of steps. The dome was also very commonly employed rather than the pent roof. The following is an example of a temple at Rome.

27. Greco-Gothic style.—After the dismemberment of the Roman empire, the practice of erecting new buildings from the fragments of old ones became prevalent. This gave rise to an irregular style of building, which continued in use during the dark ages. It consisted of Greek and Roman details combined under new forms, and piled up into structures wholly unlike the original buildings from which the materials had been taken. Hence the appellations Greco-Gothic and Romanesque have been applied to it. The effect of this style of building was very imposing, especially when columns and arches were piled upon each other to a great height.

28. Saracenic style.—This appellation has been given to the style of building practised by the Moors and Saracens in Spain, Egypt, and Turkey. It is distinguished, among other things, by an elliptical form of the arch. A similar peculiarity exists in the domes of the Oriental mosques, which are sometimes large segments of a sphere, appearing as if inflated; and at other times, they are concavo-convex on the outside. Several of these domes are commonly placed upon one building. The minaret is a tall slender tower, peculiar to Turkish architecture.

29. Gothic style.—The Goths, who overran a great part of the Western empire, were not the inventors of the style of architecture which bears their name. The term was first applied with the view to stigmatize the edifices of the middle ages, in the construction of which, the purity of the antique models had not been regarded. The term was at first very extensive in its application; but it is now confined chiefly to the style of building which was introduced into various parts of Europe six or eight centuries ago, and which was used in the construction of cathedrals, churches, abbeys, and similar edifices.

30. The Gothic style is peculiarly and strongly marked. Its principles seem to have originated in the imitation of groves and bowers, under which the Druid priests had been accustomed to perform their sacred rites. Its characteristics are, pointed arches, pinnacles and spires, large buttresses, clustered pillars, vaulted roofs, and a general predominance of the perpendicular over the horizontal.

31. The ecclesiastical edifices of this style of building are commonly in form of a cross, having a tower, lantern, or spire, erected at the point of intersection. The part of the cross situated towards the west is called the nave; the eastern part, the choir; and the transverse portion, the transept. A glance at the following diagram will enable the reader to understand the form of the ground-work more fully.
