The doors of this secret apartment, and the adjacent antechamber, were guarded by six deformed Nubian slaves, whose writhen and withered countenances formed a hideous contrast with their snow-white dresses and splendid equipment. They were mutes, a species of wretches borrowed from the despotism of the East, that they might be unable to proclaim the deeds of tyranny of which they were the unscrupulous agents. They were generally held in a kind of horror, rather than compassion, for men considered that slaves of this sort had a malignant pleasure in avenging upon others the irreparable wrongs which had severed themselves from humanity. It was a general custom, though, like many other usages of the Greeks, it would be held childish in modern times, that by means of machinery easily conceived, the lions, at the entrance of a stranger, were made, as it were, to rouse themselves and roar, after which a wind seemed to rustle the foliage of the tree, the birds hopped from branch to branch, pecked the fruit, and appeared to fill the chamber with their carolling. This display had alarmed many an ignorant foreign ambassador, and even the Grecian counsellors themselves were expected to display the same sensations of fear, succeeded by surprise, when they heard the roar of the lions, followed by the concert of the birds, although perhaps it was for the fiftieth time. On this occasion, as a proof of the urgency of the present meeting of the council, these ceremonies were entirely omitted. The speech of the Emperor himself seemed to supply by its commencement the bellowing of the lions, while it ended in a strain more resembling the warbling of the birds.
