In the intervals, when the tumult of weak voices was partially lulled, there was heard a dull, regular, beating sound, produced by those who had found dry bones on their road to the palace, and were pounding them on the pavement, in sheltered places, for food. The wind, which had been refreshing during the day, had changed at sunset, and now swept up slowly over the street in hot, faint gusts, plague-laden, from the East. Particles of the ragged clothing on some prostrate forms lying most exposed in its course waved slowly to and fro, as it passed, like banners planted by Death on the yielding defences of the citadel of Life. It wound through the open windows of the palace, hot and mephitic, as if tainted with the breath of the foul and furious words which it bore onward into the banqueting-hall of the senator's reckless guests. Driven over such scenes as now spread beneath it, it derived from them a portentous significance; it seemed to blow like an atmosphere exuded from the furnace-depths of centre earth, breathing sinister warnings of some deadly convulsion in the whole fabric of Nature over the thronged and dismal street. Such was the prospect before the palace, and such the spectators assembled in ferocious anxiety to behold the destruction of the senator's abode. Meanwhile, within the walls of the building, the beginning of the fatal orgie was at hand. It had been covenanted by the slaves (who, during the calamities in the besieged city, had relaxed in their accustomed implicit obedience to their master with perfect impunity), that, as soon as the last labours of preparation were completed, they should be free to consult their own safety by quitting the devoted palace. Already some of the weakest and most timid of their numbers might be seen passing out hastily into the gardens by the back gates, like engineers who had fired a train, and were escaping ere the explosion burst forth. Those among the menials who still remained in the palace were for the greater part occupied in drinking from the vases of wine which had been placed before them, to preserve to the last moment their failing strength.
