The expenditure of Nikias was all calculated to increase his popularity in the state, being devoted to offerings to the gods, gymnastic contests and public dramatic performances. But all the money he spent that way, and all that he possessed was but a small part of what Crassus bestowed upon a public feast at Rome for some tens of thousands of guests, whom he even maintained at his own cost for some time after. So true it is that wickedness and vice argue a want of due balance and proportion in a man's mind, which leads him to acquire wealth dishonestly, and then to squander it uselessly.

II. So much for their riches. Now in their political life, Nikias never did anything bold, daring or unjust, for he was outwitted by Alkibiades, and always stood in fear of the popular assembly. Crassus, on the other hand, is accused of great inconsistency, in lightly changing from one party to another, and he himself never denied that he once obtained the consulship by hiring men to assassinate Cato and Domitius. And in the assembly held for the dividing for the provinces, many were wounded and four men slain in the Forum, while Crassus himself (which I have forgotten to mention in his Life) struck one Lucius Annalius, a speaker on the other side, so violent a blow with his fist that his face was covered with blood. But though Crassus was overbearing and tyrannical in his public life, yet we cannot deny that the shrinking timidity and cowardice of Nikias deserve equally severe censure; and it must be remembered that when Crassus was carrying matters with so high a hand, it was no Kleon or Hyperbolus that he had for an antagonist, but the great Julius Cæsar himself, and Pompeius who had triumphed three several times, and that he gave way to neither of them, but became their equal in power, and even excelled Pompeius in dignity by obtaining the office of censor. A great politician should not try to avoid unpopularity, but to gain such power and reputation as will enable him to rise above it.

Yet if it were true that Nikias preferred quiet and security to anything else, and that he stood in fear of Alkibiades in the assembly, of the Spartans at Pylus, and of Perdikkas in Thrace, he had every opportunity to repose himself in Athens and to "weave the garland of a peaceful life," as some philosopher calls it. He had indeed a true and divine love of peace, and his attempt to bring the Peloponnesian war to an end, was an act of real Hellenic patriotism. In this respect Crassus cannot be compared with Nikias, not though he had carried the frontier of the Roman empire as far as the Caspian and the Indian seas.
