chapter, choose an example, which will apply to us, as well as to any other branch of the Church, to show how essentially church architecture in that respect at least is a part of the Ritual system. And if Catholic worship is expressed and represented by Catholic ritual, and if church architecture is a part of this ritual, then is church architecture itself an expression and exponent of Catholic worship. A conclusion this which will well warrant the very strong language in which the Cambridge Camden Society have always asserted the great importance of this art, and have exacted from its professors such qualifications of personal holiness and liturgical knowledge as are no less above the attainment than the aspirations of the modern school. It may not be clear to some how in any sense architecture can be called symbolical, or the outward sign of something invisible: or rather what the process is by which a given arrangement, suggested perhaps by some necessity, becomes in turn suggestive and figurative of the very purpose for which it was planned. But let us take the case of a theatre. Here it is clearly necessary that there shall be a stage or orchestra, accommodation for spectators, and means of easy exit. {lvii} Accordingly every theatre displays all these requisites. And does not the building then in turn emblem the purpose for which it was planned? The ruins of Roman theatres are not uncommon: do we fail to be recalled by them to the idea of the Roman stage? are not the several parts of the material building highly figurative and suggestive of the rules and orders of the abstract drama?
