CH. 18 AL-KAHF otherwise known as Alexander's wall, blocking the narrow pass of the Iron Gate or the Caspian Gate. This, when entire, had a height of 29 feet and a thickness of about 10 feet, and with its iron gates and numerous watch-towers formed a veritable defence of the Persian Frontier. This extract shows that there existed a wall which served as a barrier against, and protected Persia from, the attacks of the Scythians in the north. It is generally believed that this was built by Alexander the Great but this popular belief is against proven facts of history. Alexander defeated Darius in the summer of 330 B. C. , but this defeat did not give him possession of the whole of Persia. Without pausing to take rest he proceeded to subdue the whole country, but had hurriedly to come back to quell a revolt in his rear. After this he marched on to Kabul, where he had to face another revolt in his army and it was only in the winter of 329 B. C. , that he could come to India. He finished all this journey in such haste that some historians have doubted whether it could have been accomplished in such a short time. Anyhow, it is admitted that he fought his way to India and did not stop anywhere. From India he returned in 324 B. C. to Persia, where he had again to face a revolt in his army. After subduing it he started for home and died on the way in June, 323 B. C. (Enc. Brit. , 14th edition, vol. 1, pp. 569, 570). These facts show that his military expeditions were like a whirlwind and he conquered a large part of the world in a very short time. PT. 16 Amidst these whirlwind expeditions he could not give attention to any vast project such as the building of a large wall of the nature of that under discussion. The popular notion that Alexander had built this wall seems to have arisen from the fact that Muslim commentators of the Quran mistook Dhul-Qarnain for Alexander. But if Alexander did not build this wall it does not prove that Cyrus built it. We are not in possession of quite incontestable and conclusive show that historical evidence to Cyrus did build this wall. Our conclusion that he was its builder is only on the following based circumstantial evidence: (a) Darius about whom Cyrus had seen a vision that his wings would overshadow Europe and Asia ascended the Persian throne after the death of the son of Cyrus. In order to break the power of the Scythians Darius passed through Greece and attacked them prom across Europe. It is inconceivable that Darius should have undertaken such a long, arduous and roundabout journey to attack these people from across south-east Europe when they lived very near him in the north. The inevitable conclusion is that the existence of a huge wall which only Cyrus before him could have built had made it impossible for him to cross over to the other side with a large force. Nor was it possible for him to demolish it or take his army safely through its gates. So in order to fulfil his mission the only possible and wise cause open to Darius was to attack the Scythians from the side of Europe. 1904 (b) If there existed no impassable
