Relatively to the super-terranean constructions these excavations appear as prior in time, so that we may regard the enormous spaces laid out above the soil as an imitation and efflorescence of similar tracts of land beneath it. In excavations there is no positive building, but we have rather a given material taken away. And to nest thus in the ground, to excavate is more natural to man than to seek for a material, and with it to construct and inform a mass of buildings. In this respect we may assume the cave to be utilized prior to the hut or dwelling. Caves are the extension of spatial covering instead of a limitation of such, or an extension which grows up as a limit and enclosure, in which the enclosure is already present. The subterranean construction consequently inclines to start with what is already present, and, in so far as it leaves the fundamental material as it finds it, is not erected with the freedom applicable to a configuration raised above the surface of the soil. In our view, however, these constructions already belong to a further stage of the art of building, however much they may also have features of a symbolical type, because they no longer are placed there as independently symbolical, but already possess the aim or purpose of an enclosure, a partition, a roof, within which more symbolical figures as such are set up. That which is connoted under the conception of temple and dwelling, both in the Greek and more modern use of the terms, we have here in their most natural form.
We may include in the above class the caves of Mithras, although we find them in a very different locality. The worship and ritual of Mithras originates in Persia. A cultus, however, of a similar kind was also promulgated in the Roman Empire. In the Paris Museum we find a very famous bas-relief, which represents a youth in the act of striking an ox with a steel weapon. It was discovered in the Roman Capitol in a deep grotto beneath the temple of Jupiter. In these Mithras caves vaults are also met with, and passages which on the one hand appear definitely to symbolize by suggestion the course of the stars, and from another point of view also (precisely as still in our own time takes place in our free-mason lodges, where people are conducted through many passages and have to see dramatic scenes and much else) the ways, which the soul must pass through in its purification, albeit it may be true enough that this fundamental meaning is more fully and directly expressed in sculpture and other work than in architecture simply. In a connection somewhat similar we may also mention the Roman catacombs, the fundamental idea of whose construction was certainly something quite other than that of being subservient to aqueducts, sepulchres or any system of drainage.
(b) In the second place we may seek for our present use a more definite point of transition from the architecture of independent type in those constructions which have been raised as housings of the dead, partly in the form of excavations beneath the ground, and partly as buildings above it. More particularly among the Egyptians this kind of construction, whether subterranean or super-terranean, was associated with a realm of the dead, just as in general among the Egyptians it is a realm of the invisible which in the first instance receives a habitation and is placed before us. The Hindoo burns his dead, or suffers their bones to lie and moulder on the earth. According to the Hindoo's point of view mankind are, or become, god or gods, whichever way one cares to put it, and we are unable to find in their case this assured distinction between the living and the dead regarded as dead. Hindoo constructions, consequently, so far as they do not originate in Mohammedanism, are not dwellings for the dead, and appear generally to belong to an earlier period as we assumed was true of the astonishing excavations described. In the case of the Egyptians, however, the contrast between living and dead asserts itself predominantly. That which is spiritual begins to separate itself essentially from what is material. We have here the resurrection of spirit in concrete individuality, the movement of that process. The dead are therefore retained fast as personality[57], and are secured and preserved securely above the conception of dissolution into Nature, that is into universal evanescence, flood and extinction. Singularity is the principle of the spiritual in its notion of independence, because spirit is only able to exist as individuality, that is personality. Consequently this honour paid to and preservation of the dead can only appear to ourselves as a first and important element in the definition of the existence of spiritual individuality, since it is here that singularity is asserted as maintained rather than abandoned, inasmuch as the body at any rate is treasured and respected as this Nature's own mode of individuality. Herodotus assures us, a fact we have already noticed, that the Egyptians were the first to declare that the souls of men were immortal, and despite the fact that the grasp on spiritual individuality is in their case very incomplete, in so far as in their view the deceased must for three thousand years pass through a whole series of animals belonging to land, water, and air, yet for all that in this conception, and in the embalming of the body, we find fixedly the notion of bodily individuality, and of the independent self-existence as separate from that body.
It is therefore also of importance in the arts of building that in these the separation of the spiritual, no less than the ideal significance, which[58] is independently represented, be carried into effect while the corporeal shell is set round it as a purely architectonic environment. The dwellings of the dead of the Egyptians constitute for this reason the earliest examples of the temple type. The essential feature, the central core of worship is a subject, an individual object which appears of significance by itself, and expresses itself as distinct from its dwelling, which is thereby interpreted as purely a subservient covering. And no doubt it is not an actual man, for whose requirements a house or palace had to be built, but deceased objects that are without such needs, kings, sacred animals, around whom immeasurable constructions are enclosed.
Just as agriculture fixes the wandering of nomads in the stable possession of a definite locality, we may say that generally sepulchres, monuments, and the service of the dead unite mankind, and even offer to those who possess no States, no limitations of property, a place of rendez-vous, sacred places which they defend and refuse to have taken away from them. As an illustration we may cite the case of the Scythians, a nomad people, who retired everywhere, according to the narration of Herodotus[59], before Darius. And when Darius sent an embassage to them with the message that if their king deemed himself strong enough to offer resistance he should come forth to battle, but if he did not he ought to recognize Darius as his lord, Idanthyrsus met the same with the reply that they possessed neither cities nor tilled land, and had nothing to defend for the reason that Darius had nothing to ravage; if, however, Darius made a point of having a fight they possessed the sepulchres of their fathers, let him therefore dare to advance against these, he will then discover whether they will fight for their sepulchres or not.
The most ancient and imposing monuments erected to the dead we find in Egypt. They are the Pyramids. What most excites our wonder at first sight of these astonishing constructions is their extraordinary magnitude, which at once makes us reflect upon the duration of time, the variety, superabundance and persistence of human energies which is inseparable from the completion of such colossal buildings. From the point of view of form there is nothing in them to protract attention: in a few minutes we have surveyed and taken in the entire effect. With this simplicity and uniformity of their form in view their object has ever been a subject of controversy. It is true that even the ancients, as for example Herodotus and Strabo, adduced the aim, which they subserved; but for all that both in former and more recent times, travellers and writers have contributed much that is fabulous and unwarranted in their reflections. The Arabs endeavoured to effect entrance by force, hoping to discover treasure in the interior of the Pyramids; such assaults, however, beyond disturbing much, have failed in their object to reach the actual passages and chambers. Europeans of a later date, among whom we may mention in particular for distinction, Belzoni, a native of Rome, and Caviglia of Genoa, have at last succeeded in ascertaining more accurate information with respect to the interior of these fabrics. Belzoni discovered the royal sepulchre in the Pyramid of Chephren. The entrances to the Pyramids were closed in the securest way by square blocks of stone, and it appears that Egyptians endeavoured in their construction so to effect matters that the entrance, even when discovered, could only be followed up and opened with the greatest difficulty. This proves to us that the Pyramids remained closed and could not be again used. Within their interior explorers have found chambers, passages, which point by suggestion to the ways, which the soul undertakes after death in its course and transmigration, great halls, channels beneath the earth at one time descending, at another mounting up. The royal sepulchre of Belzoni runs on in this way hewn out of the rock for a mile. In the principal hall stood a sarcophagus of granite, sunk in the ground; but all that was discovered in it was the remains of animal bones of a mummy, probably that of an Apis. The whole, however, proved beyond a doubt that the object in view was that of being a dwelling for the dead. The Pyramids differ in age, form, and size. The most ancient appear to be stones piled on one another in a more or less pyramidal shape. The more recent ones are constructed with uniformity; some are somewhat flattened out at the summit, others run up entirely to a point. On others have been found deposits, an explanation of which may be gathered from the description Herodotus[60] gives us when referring to the Pyramid of Cheops of the manner in which the Egyptians carried out such works, so that Hirt includes such among the Pyramids which remained unfinished[61]. In the older Pyramids according to the latest evidence of Frenchmen the chambers and passages are more winding; in the more recent ones they are simpler, but entirely covered with hieroglyphics, to interpret which throughout will take several years.
In this way the Pyramids, despite all the wonder they arouse of their own accord, are really nothing but crystals, mere shells, which enclose a kernel, that is a departed spirit, and serve as custodians of his still consistent bodily presence and form. In this departed and deceased person, who secures an independent reproduction, we fail to find consequently any significance[62]; the architecture, however, which up to this point independently possessed its significance in itself as architecture, is now divided in its aim, and in this division is subservient to something else, whereas sculpture receives the function to give body to the genuine ideal aspect, although in the first instance the individual figure in its unique and immediate natural shape is retained. We find consequently, on a general survey of the Egyptian art of building, on the one hand, the self-subsistent symbolical buildings; on the other, however, and more particularly in everything which is attached to the monuments of the dead, the specific determination of architecture to be an enclosure and nothing more, already clearly asserts itself. It is an essential concomitant of this, that architecture not only be limited to the construction of excavations and caves, but attest itself as an inorganic Nature built by human hands on the spot where men have actual need of it, and for a definite purpose will it to be.
Other nations have raised monuments of the same kind, sacred buildings as dwellings of the dead bodies, over whom they happen to be erected. As examples we may instance the mausoleum in Curia, and of more recent date that of Hadrian, the still existing Englesburg in Rome, a palace of careful construction raised in honour of a dead person, all of which were even in antiquity famous works. According to the description of Uhden[63] we may also mention in this connection a type of mortuary, which in its arrangement and environment imitated in its smaller aspects temples dedicate to gods. A temple of this kind possessed a garden, arbours, a spring, a vineyard, and moreover chapels, in which portrait statues of gods were placed. More particularly in the time of the Roman Empire were such monuments to the dead built with statues of the deceased under the image of gods such as Apollo, Venus, and Minerva. Figures like the above, no less than the entire construction, consequently received during that age the significance of an apotheosis and a temple in honour of the dead man, just as also among the Egyptians the process of embalming, the emblems placed thereby, and the sarcophagus attest that the deceased was treated as a god-like Osiris[64].
The most imposing and least complex constructions of this kind, however, are the Egyptian Pyramids. In this type we have the peculiar and essential line of the art of building, that is the straight one, and in general terms the uniformity and abstract simplicity[65] of forms. For architecture, as merely enclosure and inorganic Nature, or Nature that is not itself vitally and essentially suffused by the indwelling spirit in an independent mode, is unable to possess form except as one which is external to itself; external form, however, is not organic, but abstract and purely referable to the organs of sense[66]. However much the Pyramid already begins to receive the determining characteristics of the dwellings, yet the rectangular principle is still not throughout predominant, as it is in a real dwelling-house; it has still an independent determinacy, which is not merely of service to the purpose for which it is erected, and consequently closes up of itself by a process of gradation directly from the foundation to the apex.
(c) It is from this point that we may make the transition from the independent type of building to that of an art of construction, which is serviceable of a purpose.
