This battle presently made a great change of affairs to Alexander's advantage. For Sardis itself, the chief seat of the barbarians' power in the maritime provinces, and many other considerable places, were surrendered to him; only Halicarnassus and Miletus stood out, which he took by force, together with the territory about them. After which he was a little unsettled in his opinion how to proceed. Sometimes he thought it best to find out Darius as soon as he could, and put all to the hazard of a battle;at another time he looked upon it as a more prudent course to make an entire reduction of the sea-coast, and not to seek the enemy till he had first exercised his power here and made himself secure of the resources of these provinces. While he was thus deliberating what to do, it happened that a spring of water near the city of Xanthus in Lycia, of its own accord swelled over its banks, and threw up a copper plate upon the margin, in which was engraven in ancient characters, that the time would come, when the Persian empire should be destroyed by the Greeks. Encouraged by this incident, he proceeded to reduce the maritime parts of Cilicia and Phoenicia, and passed his army along the sea-coasts of Pamphylia with such expedition that many historians have described and extolled it with a height of admiration, as if it were no less than a miracle, and an extraordinary effect of divine favor, that the waves which usually come rolling in violently from the main, and hardly ever leave so much as a narrow beach under the steep, broken cliffs at any time uncovered, should on a sudden retire to afford him passage. Menander, in one of his comedies, alludes to this marvel when he says, Was Alexander ever favored more?
Each man I wish for meets me at the door, And should I ask for passage through the sea, The sea, I doubt not, would retire for me.
Then he subdued the Pisidians who made head against him, and conquered the Phrygians, at whose chief city Gordium, which is said to be the seat of the ancient Midas, he saw the famous chariot fastened with cords made of the rind of the cornel-tree, about which the inhabitants had a tradition, that for him who should untie it, was reserved the empire of the world. Most authors tell the story of Alexander, finding himself unable to untie the knot, the ends of which were secretly twisted round and folded up within it, cut it asunder with his sword. But Aristobulus tells us it was easy for him to undo it, by only pulling the pin out of the pole, to which the yoke was tied, and afterwards drawing off the yoke itself from below.
Darius was by this time upon his march from Susa, very confident, in the number of his men, which amounted to six hundred thousand.
But Alexander was detained in Cilicia by a sickness, which some say he contracted from his fatigues, others from bathing in the river Cydnus, whose waters were exceedingly cold. None of his physicians would venture to give him any remedies, they thought his case so desperate, and were so afraid of the suspicions and ill-will of the Macedonians if they should fail in the cure; till Philip, the Acarnanian, seeing how critical his case was, but relying on his own well-known friendship for him, resolved to try the last efforts of his art, and rather hazard his own credit and life, than suffer him to perish for want of physic, which he confidently administered to him, encouraging him to take it boldly, if he desired a speedy recovery, in order to prosecute the war. At this very time, Parmenio wrote to Alexander from the camp, bidding him have a care of Philip, as one who was bribed by Darius to kill him, with great sums of money, and a promise of his daughter in marriage. When he had perused the letter, he put it under his pillow, without so much as showing it to any of his most intimate friends, and when Philip came in with the potion, he took it with great cheerfulness and assurance, giving him meantime the letter to read. This was a spectacle well worth being present at, to see Alexander take the draught, and Philip read the letter at the same time, and then turn and look upon one another, but with different sentiments; for Alexander's looks were cheerful and open, to show his kindness to and confidence in his physician, while the other was full of surprise and alarm at the accusation, appealing to the gods to witness his innocence, sometimes lifting up his hands to heaven, and then throwing himself down by the bedside, and beseeching Alexander to lay aside all fear, and follow his directions without apprehension. For the medicine at first worked so strongly as to drive, as it were, the vital forces into the interior; he lost his speech, and falling into a swoon, had scarcely any sense or pulse left. However, in a very short time, by Philip's means, his health and strength returned, and he showed himself in public to the Macedonians, who were in continual fear and dejection until they saw him abroad again.
