Before considering the Umayyad ḥîrahs of the western desert three other Sasanian buildings must be passed briefly under review. I will deal first, though it is not first in date, with the second palace at Qaṣr-i-Shîrîn, Chehâr Qapû.
Is it a palace? A glance at the plan is enough to prove that it does not fall precisely within the four corners of the scheme to which Khusrau’s palace belongs. This divergence of plan, and the peculiar character imparted to the ruins by the isolated quadrangular chamber which dominates the whole complex, have led to the suggestion that Chehâr Qapû may have been a fire temple. In support of this view two buildings have been cited, the rectangular western annex at Hatra, and a ruin excavated by Dieulafoy at Susa. The last-named instance carries little weight.[161] Its resemblance to Hatra depends upon the reconstruction proposed by Dieulafoy upon data too slight to be convincing. Until a further examination has been made, the ruin at Susa offers too frail a substructure for the lightest of theories. As regards Hatra ([Fig. 10]), the western annex blocks a window in one of the smaller rooms of the south lîwân and is therefore certainly a later addition. But the learned author of the Deutsche Orient-Gesellschaft publication has given us two plans of smaller palaces, found among the ruins in the city, of which one certainly, and the other probably, is composed of a lîwân with its flanking chambers, and a posterior rectangular room with, however, the interposition of a narrow latitudinal room between them ([Fig. 18]). Dr. Andrae has pointed out that while a lîwân group combined with a rectangular chamber, but without a latitudinal chamber, exists in the main palace (south lîwân), two lîwâns with a latitudinal chamber but without the rectangular chamber are found in the northern annex, which, like the western annex, is a later addition to the palace. The fact that the dispositions observed in the main palace are not entirely isolated examples is of the highest significance, but it does not solve the problem connected with the so-called ‘temple’. In all these palaces the posterior quadrangular chamber may have been a sanctuary, or it may equally well have been a living-room. The theory that in the main palace it is indeed a sanctuary rests mainly upon the symbolic representations carved upon the lintel of one of its doorways.[162] The motives there used are familiar elements of Parthian decoration. The dragon occurs upon the façade of Hatra itself and was found by Loftus among the Parthian fragments at Warka,[163] as well as upon a lintel excavated by George Smith at Quyundjik,[164] but there is no saying whether the lintel belonged to a sanctuary or to a private dwelling. Nor is there much to be learnt, with regard to fire temples, from literary sources. Herodotus declares that it was not the practice of the Persians

to erect statues, temples, or altars;[165] Strabo that they erect neither statues nor altars, but, considering the heaven as Jupiter, sacrifice on a high place. Strabo goes on, however, to state that they have large shrines called Pyraetheia, in the middle of which the Magi, entering daily into the shrine, maintain an inextinguished fire.[166] Trustworthy architectural data for such buildings we do not possess, and as Dr. Andrae has observed, the rectangular chamber at Hatra is unlike any other temple known to us, either in the East or in the West.[167] In the outer court of the palace he found a ruin which he calls tentatively an âteshgâh (fire altar).[168] It is a block of masonry almost square which stood 10 to 12 metres high and has traces of a stair that may either have wound round three sides of the tower, or have zigzagged up the face on one side only. He compares it with the tower some 28 metres high at Djûr, near Firûzâbâd, which was published by M. Dieulafoy[169]. The Djûr tower may date from the time of Ardeshîr Bâbagân, A.D. 227-240. Here, too, there was a stair, which must have wound three times round the tower in order to attain the platform at the summit. M. Dieulafoy was struck by the resemblances that existed between the tower at Djûr, the ziggurat at Khorsâbâd, and the minarets at Sâmarrâ and at Cairo.[170] A ramp winding round the ziggurat to the summit of the pyramid is described by Herodotus, but has not yet been assured by excavation, and even the existence of pyramids with platforms at various heights among the ruins hitherto examined is doubtful.[171] The whole question of fire altar and fire temple is therefore very obscure. The towers at Djûr and at Hatra may have been sacrificial altars, and Strabo bears witness to the fact that the Persians sacrificed in a high place; but I find it difficult to believe that they can have been intended for an inextinguished fire. To keep a fire alight in so exposed a spot would have taxed the ingenuity of the Magi beyond endurance. The shrines in which the perpetual fire burnt must have afforded better shelter, but what shape they assumed we do not know. No help can be expected from this quarter, and the problem presented by Chehâr Qapû must be considered on its merits. It is slightly cleared by a recognition of the fact.
The quadrangular chamber of Chehâr Qapû, viewed impartially, does not offer any serious difficulty. If the audience hall in the palace of Khusrau were standing, its aspect would be much the same, for it too was a large square chamber with a dome rising above and dominating the rest of the palace. At Sarvistân a parallel structure exists to this day. But it is the surrounding buildings which are different, and the question is further complicated by the circumstance that the rooms in the immediate vicinity of the domed hall are so much ruined that their exact arrangement cannot be decided without some excavation—it is provoking to think how little excavation would be needed. So far as can be observed at present Chehâr Qapû is a rectangular complex with the main entrance to the east; the gateway is flanked to the south by two courts, to the north by one, each court being furnished with small rectangular rooms. I conjecture that these were guard-rooms, and they may be compared with the rooms under the ramps in the palace of Khusrau. The main entrance opened into a long quadrangular court with a monumental gate at the further end. To the north of this court, and communicating with it by a door at the eastern end, there is an almost quadrangular area, formed by rooms set round the courtyard numbered E on the plan. The rooms are latitudinal, and they bear no resemblance to the lîwâns of the palace of Khusrau. To the west lies another court, F, with latitudinal rooms on two sides and an independent communication with the entrance court; still further west are two smaller courts, G and H, with rooms on two sides; and finally, to the north of the domed hall, there seems to have been a fifth court or open space with rooms on two sides. The south wing is not symmetrical with the north wing and it is considerably wider. There are three large courts here. Court I has chambers on three sides; those on the south side resembling a lîwân group with a ṭarmah. Court J has on the south side a latitudinal chamber, with a ṭarmah on the north side, and a passage communicating with the entrance court, A. Court K has a lîwân group with a ṭarmah on the south side; the north and west sides are ruined. Beyond this lies a totally ruined area, to the west of which stand two rooms, apparently with a ṭarmah, and at the south-west end of the palace there is a series of four rooms. With the exception of the small courts on either side of the main gate, all the courts seem to have had some direct intercommunication; this was probably the case in the palace of Khusrau also. The grouping of the rooms in the court is, however, almost entirely unlike that which has been described in the larger palace at Qaṣr-i-Shîrîn, at Ukhaiḍir, or at Sâmarrâ. Courts I and K alone, with their lîwâns and ṭarmahs, offer shadowy resemblances to the others. The arrangement of the rooms, the irregularity of the areas covered by the courts, and the tendency towards an asymmetrical disposition, point to a reversion to the methods of the ancient East. Symmetry plays no part in the palace-planning of Babylonia and Assyria. From the earliest to the latest, from the Chaldaean palaces[172] to the palace of Nebuchadnezzar at Babylon,[173] through all the intervening palaces in Assyria, at Nimrûd, at Quyundjik, at Khorsâbâd and at Assur, no principle of symmetry is to be observed. Nor yet is it to be found, except quite fortuitously, in the Hittite khilâni palaces (the late khilâni, north-west of G in Fig. 5, is one of the few instances), although they originated in the symmetrical gateway; and it is markedly absent in the northern Hittite palaces and temples at Boghâz Keui, though in other respects they have little in common with the southern Hittite monuments.[174] Assyrian temples more nearly approach to a symmetrical disposition, but only under influences foreign to Assyria, influences which can be traced back to the end of the twelfth century before Christ in the Anu-Adad temple at Assur. The old Assyrian scheme, of which we have one example in the temple of Assur, at Assur, built by Shamshi-Adad, was derived from the Babylonian temple plan and, like the Babylonian, it was asymmetrical. The imported plan is characterized by the substitution of longitudinal for latitudinal chambers.[175] But these foreign, probably Western influences (for they were responsible also for the creation of Solomon’s temple, apparently a symmetrical building),[176] could not reduce Assyrian architecture to an ordered plan, and the temples in Sargon’s palace at Khorsâbâd fall far short of symmetry,[177] while in Babylonia the longitudinal chamber, i.e. the imported plan, was never adopted, and until the latest period, the temples, like the palaces, remained entirely unsymmetrical.[178] The plan of Quyundjik, which is the most complete record of any Assyrian palace which has yet been published, throws considerable light upon Chehâr Qapû ([Plate 77]). Courts XXVII and XXX in the temple area, courts XVIII, XIX, XX, and XXII in the domestic quarters, exhibit an unsymmetrical grouping of latitudinal and longitudinal chambers very much akin to that of the courts of Chehâr Qapû. In court XVI we have a foreshadowing of the ṭarmah scheme. (Place believes the rooms in court XVI to have been storehouses for wine, from the quantity of jars found in them.)[179] It would be ridiculous to push a minute comparison too far, seeing that a period of over 1,000 years separates the two buildings, but a certain resemblance in details and, still more, a general correspondence on the fundamental principle of asymmetry leads me to suspect that a primaeval tradition survived through all the innovations of Greece or Rome, Parthia or Persia, and that, at the end of the sixth century, it had sufficient vitality to guide the craftsmen to Khusrau Parwêz in the composition of a monumental building. Survivals of this nature are not infrequently connected with hieratic tradition, and if my conjecture is correct it might serve in some measure to support the claim to a non-secular character which had been put forward for Chehâr Qapû, although the domed hall, which we must assume to have been the sanctuary, bears no resemblance to the cella and anteroom of the Babylonian or of the Assyrian temple. It would be necessary to postulate that while the Sasanian builder retained in the courts and chambers of his temenos something of an ancient tradition which had come to be regarded as sacred, he gave to the shrine wherein the holy element burned with a perpetual flame the form which had been assumed by the ceremonial dwelling of the divine Chosroës.
The two remaining Sasanian buildings which it will be necessary to mention are Ctesiphon and Karkh. Ctesiphon is the most famous of all the later Persian palaces ([Fig. 19]). It was erected by Shapûr I (A.D. 242-272)[180] and is therefore about 100 years later than Hatra, and earlier than Qaṣr-i-Shîrîn by some 250 years. Not only chronologically, but also in plan, it is closely related to the Parthian palace. It reproduces in yet more striking dimensions the simple lîwân scheme, of which Hatra offers the earliest monumental example. The lîwân at Ctesiphon is covered by a vault spanning 25·80 metres, a dimension which was not exceeded in Rome itself. On either side of the lîwân five vaulted chambers were set at right angles; rising in stories their vaults abutted the main vault, as at Firûzâbâd and Ukhaiḍir. The side chambers had an independent entrance in the façade, a system which was first employed at Hatra. The masonry is of brick, chained with wooden beams as at Ukhaiḍir; but at Ctesiphon the beams are placed parallel with the coursing of the masonry, whereas at Ukhaiḍir they are inserted at right angles into the walls.
