The system of Roman organisation at first modified and finally broke up the old tribal communities. For some time, many old-world institutions were maintained, notably the priest-dynasts of Comana, Olba, and Venasa; but gradually the native communal temple-district organisation of society gave way, to be replaced by the Greek political system, the seeds of which had been planted two or three centuries before, and had now taken root. In this system the city became the administrative centre, and the villages around were its branches. Greek became more and more the language of the people.[115] The formal records of military works, the milestones and imperial monuments, are inscribed in Latin, but the inscriptions in the old graveyards are carved in Greek letters. We cannot dwell upon the history of these times, of the reorganisation under Diocletian, at the close of the third century, marking the commencement of the Byzantine period, nor of the spread of Christianity, with the great social changes that involved. We reproduce, however, some illustrations of Roman works, such as are met with in plenty throughout the length and breadth of Hittite lands, from Malatia to Iconium and beyond, from Tarsus to the Black Sea coast. The great aqueducts like those of Tyana,[116] and those which stretch for miles across the Cilician plain,[117] are an indication of the vast scheme of development that was instituted under the new well-ordered system of government. Great cities both in Syria and in Asia Minor were the product of these times. Many of these were the foundations of places that still remain centres of administration; while some have lost their importance, and are falling gradually to ruin in silence and desolation. The remains of Kyrrhus upon the Afrîn,[118] a site now marked only by the small village of Huru-Pegamber some distance away, are among the wonderful memorials of antiquity. The imposts are falling from their pilasters, and the keystones to its arches are working loose, but it retains its silent streets of impressive stone buildings, its arches and colonnades, its amphitheatre, as though its people had quitted hardly a generation ago. Numerous Greek inscriptions may still be found amongst the ruins,[119] and just southward of the Acropolis several sarcophagi of marble, with Greek names upon them, indicate the position of the old-time burying place. In the extreme south of the site, with its sanctity still maintained in a modern Mohammedan shrine and well adjoining, there stands perfect a tomb-structure[120] in the Roman style of the second century A.D. We give a photograph of this, which is one of the best-preserved examples of its kind. Our other photographs[121] taken at Ephesus and at Ba’albec,[122] at the two ends of the Hittite lands, will sufficiently illustrate the art and civilisation of their time and place.
