In view of this definition, it may be asserted that architecture itself is one of the industrial arts. The first duty of the constructor is to make his building well fitted for the object it has to serve. The house must afford a proper shelter for its inhabitants, the tomb must preserve the corpse entrusted to it from all chance of profanation, the temple must shield the statue or the symbol of the god from curious glances, and afford convenient space for ritual celebrations. These requirements may be fulfilled by edifices which have no pretensions to beauty. With a roof and a certain number of naked walls, it is always possible to cover and enclose a given space, and to divide it into as many portions as may be desired. Such a process has nothing in common with art. Art steps in when the builder attempts to endow his work with that symmetry which does not exclude variety, with nobility of proportion, and with the charm of a decoration in which both painter and sculptor play their parts. The constructor then gives place to the architect. The latter, of course, always keeps the practical end in view, but it is not his sole preoccupation. The house, as he builds it, has to respond to all the wants, intellectual as well as corporeal, of civilized man; the tomb must embody his ideas of death and a future life; the magnificent dimensions and the gorgeous decorations of the temple must give expression to the inexpressible, must symbolize the divine majesty to the eyes of men, and help to make it comprehensible by the crowds that come to sacrifice and pray. In all this, the _rôle_ played by art is so preponderant that it would be unjust to class architecture among the industrial arts. The ambition of those who built the temple of Amen, at Karnak, or that of Athené, on the Acropolis, was to produce a work which should give faithful expression to the highest thoughts which the human mind can conceive. In one sense, architecture may be called the first of the arts. In those great compositions whose remains we study with such reverence, whose arrangements we endeavour with such care to re-establish, it was the architect who determined what part the painter and the sculptor should take in the work, who laid out for them the spaces they were called upon to fill.
