"Is she not fair, my daughter of a year?" cried Coeur de Lion proudly as he gazed on Chateau Gaillard: and to build Chateau Gaillard in one year was certainly a fine achievement, yet it was as nothing in comparison to the building of Daras in three. It gives us a great idea of the resources of the Byzantine Empire that Anastasius, an undistinguished, albeit a conscientious, ruler should have been able to bequeath to us so superb a monument of his power. Dara is very similar in site, as it is accidentally similar in name, to another Roman foundation, the town of Daroca in Aragon. It lies pooled in a cup-like depression between the two rims of high ground which are crested with its formidable ramparts; and through the midst of it flows the little river, which cannot be diverted anywhere and thus ensures a constant water-supply. At either end of the depression the ramparts stoop from their opposing heights and join hands with each other across the stream. At these points the water is admitted and discharged through cunningly contrived water-gates consisting of several small arches, once defended by metal grilles the mortices for which may still be seen. Formerly no doubt these arches could be closed by sluices. Thus a wide and deep inundation could be formed without the walls at the upper gate, which would provide additional protection; and a similar reservoir could be collected within the walls at the lower gate, and discharged to overwhelm any battering engines that might be advanced against the city from the plain. The walls which crown the flanking heights are of singularly massive construction, and defended by a deep wide moat cut out of the solid rock. As at Diarbekr and Urfa (and in Spain at Lugo and Astorga) they are strengthened at frequent intervals by solid projecting round towers. Within the city itself are some even more notable monuments. The builders of the fortress did not rely exclusively on the river for their water-supply, but provided a huge underground cistern, fed by a rock-hewn conduit and capable of storing nearly five million gallons at need. This cistern consists of ten parallel vaulted tunnels, each about 150 feet long and 13 to 14 feet wide, with an internal height of 40 feet from the floor to the crown of the vault. The division walls of this structure are thickly encrusted with lime deposit, thus proving conclusively the purpose for which it was designed. [Illustration: CROSS SECTION _GREAT GRANARY OF DARAS_]
