These enamels, as also those of the lions and of fragments of the crenelated staircase, are now all in the Louvre, and retain sufficient of their pristine effect to suggest a scheme of colour and of decorative treatment of the greatest beauty.[96] The inscriptions round the bases of the pillars had already informed us that the hall was erected by Darius and Xerxes, but repaired and restored by Artaxerxes Mnemon, who added the inscriptions. This has been confirmed by another inscription under the lions on the pylons; these M. Dieulafoy attributes to Xerxes, as fragments of enamelled bricks of burnt clay, and not beton, and therefore of an earlier building, have been utilised as a filling-in. In all probability the hall of this palace is the identical hall in which the scenes described in the Book of Esther took place. The foundations of other parts of this palace might be no doubt laid bare by further excavations; but the ruin of the place has been so complete, that little of interest in an architectural point of view can be looked for. Below these Persian ruins are probably buried the remains of long-preceding dynasties, which deeper excavations would lay bare, and which would in all probability afford a rich harvest to the historical explorer. FIRE TEMPLES. Near the town of Istakr, and opposite the tombs of Naksh-i-Rustam, stands a small tower-like building, represented in Woodcut No. 100. The lower part is solid; the upper contains a small square apartment, roofed by two great flat slabs of stone. Access to this chamber is obtained by a doorway situated at some distance from the ground. Both the traditions of the place and the knowledge we have of their religious practices point to this as one of the fire temples of the ancient Persians. Its roof is internally still black, probably with the smoke of ancient fires, and though simple and insignificant as an architectural monument, it is interesting as the only form of a temple apart from regal state which the ancient Persians possessed. [Illustration: 100. Khabah at Istakr. No scale.] Another, almost identical in form, is found at Pasargadæ,[97] and a third exists (according to Stolze) near Maubandajan, at the foot of the Kuh Pir-i-mard, eleven miles to east of Fasa. Perrot suggests it may have been the tomb of Hytaspes, father of Darius. The celebrated Kaabah at Mecca, to which all the Moslem world now bow in prayer, is probably a fourth, while the temple represented in Woodcut No. 81, from Lord Aberdeen’s Black Stone, may be a representation of such a structure as these, with its curtains and paraphernalia complete. It is too evident, however, that the Persians were not a temple-building people,[98] and the examples that have come down to our time are too few and too insignificant on which to found any theory.
