A love of finesse and intrigue is congenital to Orientals; and, in the later period of their sway, the Persians appear to have yielded to this natural inclination, and to have used freely in their struggle with the Greeks the weapons of cunning and deception; but, in the earlier period, a different spirit prevailed; lying was then regarded as the most disgraceful act of which a man could possibly be guilty truth was both admired and practised; Persian kings, entrapped into a promise, stood to it firmly, however much they might wish it recalled; foreign powers had never to complain that the terms of a treaty were departed from; the Persians thus form an honorable exception to the ordinary Asiatic character, and for general truthfulness and a faithful performance of their engagements compare favorably with the Greeks and Romans.
The Persian, if we may trust Herodotus, was careful to avoid debt.
He had a keen sense of the difficulty with which a debtor escapes subterfuge and equivocation--forms, slightly disguised, of lying.

To buy and sell wares in a market place, to chaffer and haggle over prices, was distasteful to him, as apt to involve falsity and unfairness.

He was free and open in speech, bold in act, generous, warm-hearted, hospitable.

His chief faults were an addiction to self-indulgence and luxury, a passionate abandon to the feeling of the hour, whatever that might happen to be; and a tameness and subservience in all his relations towards his prince, which seem to moderns almost incompatible with real self-respect and manliness.
The luxury of the Persians will be considered when we treat of their manners.

In illustration of the two other weak points of their character, it may be observed that, in joy and in sorrow, they were alike immoderate; in the one transported beyond all reasonable bounds, and exhibiting their transports with entire unreserve and openness; in the other proportionately depressed, and quite unrestrained in the expression of their anxiety or misery.
