This must suffice as a description of the articulate structure of the whole. In a cathedral of this type there is space enough for an entire people. For here it is the intention that the community of a city and district do not congregate round the building, but within the same. And for this reason all the varied interests of life which in any way come into contact with religion have, too, a place assigned them. No fixed divisions of seats placed in rows divide and diminish the broad space, but everyone comes and departs in peace, engages for himself or takes a seat for immediate use, kneels down, offers his prayer and removes himself once more. If it is not the hour of high mass the most various things take place at the same time, and there is no confusion. In one portion a sermon is delivered, in another a sick man is brought in; between these points we may find a slow procession; at one spot, we have a baptism, at another a deceased person is carried through the church. Or we may find in one place a priest delivering mass or celebrating the marriage services and in every direction the people in broken groups kneel before altars and sacred images. All such things are embraced by one and the same building. But this very variety and individualization disappears, nevertheless, with its alternations when contrasted with the expanse and size of the building. Nothing completely fills up the whole, every incident passes by; individuals with all that they do are lost and dispersed as points in this grandiose whole. What happens at a given time is merely visible in its passing flight, and over and above all the huge and almost measureless spaces soar up in their secure and immutable form and construction.
Such, then, are the fundamental characteristics of the interior of Gothic churches. We must not look here for any definite purpose as such, but rather an object for the private devotion of the soul in its self-absorption in every detail of the spiritual life[106], and its elevation over all that is isolated and finite. For this reason these buildings are cut off from Nature by spaces enclosed on all sides, built up in the atmosphere of gloom and at the same time to the smallest detail in a spirit that strives upwards sublime and immeasurable.
(β) If we direct our attention now to the external aspect we shall find, as we have already above observed, that in contrast to the Greek temple the exterior configuration in Gothic architecture, the decoration and co-ordination of the walls and all else is determined from within outwards, the exterior having to appear simply as an enclosure of the interior.
In this connection we have good reason to emphasize the following points:
(αα) In the first place in the form of the cross which we find dominates the whole exterior we cannot fail to recognize in outline a similar construction as that which obtains within, a form which cuts, the nave and choir in two, and supplies, moreover, the distinctions of height which obtain between the aisles, the nave and choir.
On closer inspection we find that the principal façade, as the external form of the aisles and nave, corresponds in the portals to the particular construction within. A more lofty principal door, by which we pass direct into the nave, stands between the smaller entrances into the aisles, and suggests by means of the contraction in perspective that the exterior must draw together, grow more narrow, and disappear in order than an entrance may be thereby provided. The interior is the background already visible, into the depths of which the exterior is carried, just as the soul is constrained to grow more profound as ideality when it enters its own intrinsic wealth. Over the doors at the sides extend in the most direct connection with the interior colossal windows, just as the portals rise up to similar pointed arches, in a way similar to that in which they are employed as the particular form for the vaultings of the interior. Between these doors over the principal portal a large circular window branches out, the rose-window, a form which is, we may add, the exclusive and peculiar possession of this type of building, and only fitted to it. Where such rose-windows are absent we find substituted for them a still more colossal window with pointed arches. The façades of the transepts are divided in a similar way while the walls of the nave, the choir, and the aisles in their windows and their form, no less than in the position of the solid walls between, repeat in all respects the form of the interior and set the same forth on the outside.
(ββ) In the second place, however, the exterior begins to make itself at the same time intelligible to itself[107] in this close association with the form and subdivision of the interior for the very reason that it has its own peculiar tasks to fulfil. In this connection we may mention the flying buttresses. They represent the position of the many piers within the building and are necessary as points of support for the elevation and security of the whole. At the same time they further make apparent on the outside, so far as interval, number, and other features are concerned, the rows of piers on the inside, albeit they do not exactly reproduce the shape of the interior piers, but the higher they mount up become reduced in the strength of their springing buttresses.
(γγ) Inasmuch as, however, in the third place, it is only the interior which has to be one essentially complete enclosure, this feature is lost in the form of the exterior and makes way in every respect for the all-prevailing characteristics of continuous elevation. And for this reason the exterior receives at the same time a form independent of the interior, which asserts itself mainly in a tendency to strive upwards on all sides into points and pinnacles, breaking out in them one on the top of another. To this fundamental feature belong the lofty uplifted triangles which, independently of the pointed arches, soar upwards over the portals, pre-eminently the principal façade, though also over the colossal windows of the nave and choir, and in a similar way the slenderly pointed shape of the roof, whose gable-end is especially prominent in the façades of the transepts. Add to these the flying buttresses, which everywhere terminate in little pointed pinnacles, and in this way, just as the rows of piers within the building create a forest of stems, branches, and vaultings, on their part on the exterior stretch up heavenwards a forest of points.
With most independence and most emphatically, however, it is the towers which rise upwards in their sublime summits. In other words we find that the entire mass of the building concentrates among other things itself in them, in order that thus in its main towers it may be without hindrance uplifted to an incalculable height without thereby losing its character of repose and stability. Such towers are either placed in the principal façade over the two side entrances, while a third and broader main tower springs up at the point where the vaulting of the transepts, choir, and nave meet, or one single tower constitutes the principal façade and is raised above the entire breadth of the nave. Such are at any rate the positions which are most usual. In direct connection with the worship such towers have belfries, that is, to the extent that the ringing of bells properly applies to Christian services. This merely indefinite tone of the bell is a solemn stimulus of the soul-life, though in the first instance one that as yet prepares the worshipper only on the outside of the building. The articulate tone, on the other hand, wherein a definite content of feelings and ideas is expressed, is the song which is only to be heard within the church. The inarticulate clang of the bell finds its right place on the outside and only there and is sounded forth from the towers that its peal may pass forth as from some pure height far over the land.
(c) As to the mode of decoration I have already pointed to the main features of determinate character.
