stances; and easily ascertain the cloud to be a damp fog, or a drift of snow flakes; and the sky to be a lightless abyss. There is, therefore, no dishonesty, while there is much delight, in the irresistibly contrary impression. In the same way, so long as we see the stones and joints, and are not deceived as to the points of support in any piece of architecture, we may rather praise than regret the dexterous artifices which compel us to feel as if there were fibre in its shafts and life in its branches. Nor is even the concealment of the support of the external buttress reprehensible, so long as the pillars are not sensibly inadequate to their duty. For the weight of a roof is a circumstance of which the spectator generally has no idea, and the provisions for it, consequently, circumstances whose necessity or adaptation he could not understand. It is no deceit, therefore when the weight to be borne is necessarily unknown, to conceal also the means of bearing it, leaving only to be perceived so much of the support as is indeed adequate to the weight supposed. For the shafts do, indeed, bear as much as they are ever imagined to bear, and the system of added support is no more, as a matter of conscience, to be exhibited, than, in the human or any other form, mechanical provisions for those functions which are themselves unperceived.
But the moment that the conditions of weight are comprehended, both truth and feeling require that the conditions of support should be also comprehended. Nothing can be worse, either as judged by the taste, or the conscience, than affectedly inadequate supports—suspensions in air, and other such tricks and vanities. Mr Hope wisely reprehends, for this reason, the arrangement of the main piers of St Sophia at Constantinople. King's College Chapel, Cambridge, is a piece of architectural juggling, if possible still more to be condemned, because less sublime.
