As they passed the opening to a small cellar, Vitellius perceived some objects resembling breast-plates hanging on a wall. He looked at them with interest, and then demanded that the subterranean chambers of the fortress be thrown open for his inspection. These chambers were cut into the rocky foundation of the castle, and had been formed into vaults, with pillars set at regular distances. The first vault opened contained old armour; the second was full of pikes, with long points emerging from tufts of feathers. The walls of the third chamber were hung with a kind of tapestry made of slender reeds, laid in perpendicular rows. Those of the fourth were covered with scimitars. In the middle of the fifth cell, rows of helmets were seen, the crests of which looked like a battalion of fiery serpents. The sixth cell contained nothing but empty quivers; the seventh, greaves for protecting the legs in battle; the eighth vault was filled with bracelets and armlets; and an examination of the remaining vaults disclosed forks, grappling-irons, ladders, cords, even catapults, and bells for the necks of camels; and as they descended deeper into the rocky foundation, it became evident that the whole mass was a veritable honeycomb of cells, and that below those already seen were many others. Vitellius, Phineas, his interpreter, and Sisenna, chief of the publicans, walked among these gloomy cells, attended by three eunuchs bearing torches. In the deep shadows hideous instruments, invented by barbarians, could be seen: tomahawks studded with nails; poisoned javelins; pincers resembling the jaws of crocodiles; in short, the tetrarch possessed in his castle munitions of war sufficient for forty thousand men. He had accumulated these weapons in anticipation of an alliance against him among his enemies. But he bethought him that the proconsul might believe, or assert, that he had collected this armoury in order to attack the Romans; so he hastened to offer explanations of all that Vitellius had observed. Some of these things did not belong to him at all, he said: many of them were necessary to defend the place against brigands and marauders, especially the Arabs. Many of the objects in the vault had been the property of his father, and he had allowed them to remain untouched. As he spoke, he managed to get in advance of the proconsul and preceded him along the corridors with rapid steps. Presently he halted and stood close against the wall as the party came up; he spoke quickly, standing with his hands on his hips, so that his voluminous mantle covered a wide space of the wall behind him. But just above his head the top of a door was visible. Vitellius remarked it instantly, and demanded to know what it concealed. The tetrarch explained that the door was fastened, and that none could open it save the Babylonian, Jacim. “Summon him, then!” was the command. A slave was sent to find Jacim, while the group awaited his coming.
