(M90) Now the suspicion that the Baal of Tarsus, for all his posing in the attitude of Zeus, was really an Oriental is confirmed by a remarkable rock-hewn monument which is to be seen at Ibreez in Southern Cappadocia. Though the place is distant little more than fifty miles from Tarsus as the crow flies, yet the journey on horseback occupies five days; for the great barrier of the Taurus mountains rises like a wall between. The road runs through the famous pass of the Cilician Gates, and the scenery throughout is of the grandest Alpine character. On all sides the mountains tower skyward, their peaks sheeted in a dazzling pall of snow, their lower slopes veiled in the almost inky blackness of dense pine-forests, torn here and there by impassable ravines, or broken into prodigious precipices of red and grey rock which border the narrow valley for miles. The magnificence of the landscape is enhanced by the exhilarating influence of the brisk mountain air, all the more by contrast with the sultry heat of the plain of Tarsus which the traveller has left behind. When he emerges from the defile on the wide open tableland of Anatolia he feels that in a sense he has passed out of Asia, and that the highroad to Europe lies straight before him. The great mountains on which he now looks back formed for centuries the boundary between the Christian West and the Mohammedan East; on the southern side lay the domain of the Caliphs, on the northern side the Byzantine Empire. The Taurus was the dam that long repelled the tide of Arab invasion; and though year by year the waves broke through the pass of the Cilician Gates and carried havoc and devastation through the tableland, the refluent waters always retired to the lower level of the Cilician plains. A line of beacon lights stretching from the Taurus to Constantinople flashed to the Byzantine capital tidings of the approach of the Moslem invaders.(387)
