CHAPTER I Twilight and Dawn FROM THE 6TH TO THE IOTH CENTURY TH E Greek temple (pL i) is the most perfect example ever achieved of architecture finding its fulfilmentin bodily beauty. Its interior mattered infinitely less than its exterior. The colon- nade all round conceals where the entrance lies. The faithful did not enter it and spend hours of communication with the Divine in it, as they do in a church. Our Western conception of space would have been just as unintelligible to a man of Pericles's age as our religion. It is the plastic shape of the temple that tells, placed before us witha physical presence more intense, more alive than that of any later building. The isolation of the Parthenon or the temples of Paestum, clearly dis- connected from the ground on which they stand, the columns with their resilient curves, strong enough to carry without too much visible effort the weight of the architraves, the sculptured friezes and sculptured pediments—there is something consummately human in all this, life in the brightest light of nature and mind: nothing harrow- ing, nothing problematic and obscure, nothing blurred. Roman architecture also thinks of the building primarily as of a sculptural body, but not as one so superbly independent. There is a more conscious grouping of buildings, and parts are less isolated too. Hence the all-round, free-standing columns with their archir trave lying on them are so often replaced by heavy square piers carrying arches. Hence also walls are emphasised in their thickness, for instance, by hollowing niches into them; and if columns are asked for, they are half-columns, attached to, and that is part of, the wall. Hence, finally, instead of flat ceilings—stressing a perfectly clear horizontal as against a perfectly clear vertical—the Romans used vast tunnel-vaults or cross-vaults to cover spaces. The arch and the vault on a large scale are engineering achievements, greater than any of the Greeks, and it is of them as they appear in the aqueducts, baths, basilicas (that is public assembly halls), theatres and palaces, and not of temples that we think, when we remember Roman archi- tecture (pi, n). However, with very few exceptions, these grandest creations of
