[295] As for the furniture that was within this fortress, it was still more wonderful on account of its splendor and long continuance; for here was laid up corn in large quantities, and such as would subsist men for a long time; here was also wine and oil in abundance, with all kinds of pulse and dates heaped up together; all which Eleazar found there, when he and his Sicarii got possession of the fortress by treachery. These fruits were also fresh and full ripe, and no way inferior to such fruits newly laid in, although they were little short of a hundred years ¹ from the laying in these provisions [by Herod], till the place was taken by the Romans; nay, indeed, when the Romans got possession of those fruits that were left, they found them not corrupted all that while; nor should we be mistaken, if we supposed that the air was here the cause of their enduring so long; this fortress being so high, and so free from the mixture of all terrain and muddy particles of matter. There was also found here a large quantity of all sorts of weapons of war, which had been treasured up by that king, and were sufficient for ten thousand men; there was east iron, and brass, and tin, which show that he had taken much pains to have all things here ready for the greatest occasions; for the report goes how Herod thus prepared this fortress on his own account, as a refuge against two kinds of danger; the one for fear of the multitude of the Jews, lest they should depose him, and restore their former kings to the government; the other danger was greater and more terrible, which arose from Cleopatra queen of Egypt, who did not conceal her intentions, but spoke often to Antony, and desired him to cut off Herod, and entreated him to bestow the kingdom of Judea upon her. And certainly it is a great wonder that Antony did never comply with her commands in this point, as he was so miserably enslaved to his passion for her; nor should any one have been surprised if she had been gratified in such her request. So the fear of these dangers made Herod rebuild Masada, and thereby leave it for the finishing stroke of the Romans in this Jewish war.
