With the palace we need a closer acquaintance. Verina would be familiar with the massive iron gate on the south side of the square through which, as the Emperor rode in, one might catch a glimpse of the great bronze door of the palace. Through this gate the obscure woman of the people was now borne on her litter, to be crowned mistress of the world. The front part of the palace was burned by the people in 532, but we may assume that it had the general plan of the later structure which experts have reconstructed for us.[2] The door led into a spacious hall--known as the Chalke on account of its bronze roof--which was richly adorned with statues, marbles and mosaics. Constantine had despoiled the world to enrich his palace and city, and this entrance hall had a great store of treasures. Crossing the hall one entered the apartments of the troops who guarded the palace and whose spacious quarters formed an immense and formidable approach to the imperial palace. More than three thousand selected troops, divided into three classes, formed this imperial bodyguard, and we shall more than once find their halls swimming with blood as some frantic mob or adventurous usurper seeks to penetrate to the palace. The palace grounds were, of course, surrounded by lofty and unscaleable walls. Verina would pass first through the lines of the Scholarians, whose golden shields and lances, and gold helmets surmounted with red aigrettes, would form a glittering corridor. Ascending the marble steps at the far end of their hall, the purple curtains being drawn aside, she would pass between the Excubitors, a regiment of powerful warriors with two-edged axes, and the Candidates, or white-robed troops, gleaming with gold; the second and third lines of defence. At the end of these palatial barracks three ivory-plated doors, hung with curtains of purple silk, opened into the Consistorium, a large hall lined with marble and mosaic, in the floor of which were set porphyry slabs to indicate the successive spots where even kings must thrice prostrate themselves before approaching to kiss the feet of--Leo the Isaurian. A throne, covered with purple and heavily laden with gold and jewels, was raised under a golden dome at the upper end of the room.
