The ancients had no number whereby to express a larger sum than one hundred thousand; and at the present day, we reckon by multiples of that number, as, for instance, ten times one hundred thousand, and so on. For these multiplications we are indebted to usury and the use of coined money; hence the expressions “æs alienum,” or “another man’s money,” which we still use to signify debt, and in later times the surname “Dives,” rich: only be it known to all, that the man who first received this surname became a bankrupt and bubbled his creditors.[204] Marcus Crassus, a member of the same family, used to say that no man was rich who could not maintain a legion upon his yearly income. He possessed in land two hundred millions of sesterces, being the richest Roman citizen next to Sylla. Nor was even this enough for him, but he must want to possess all the gold of the Parthians too![205] And yet, although he was the first to become memorable for his opulence—so pleasant is the task of stigmatizing this insatiate cupidity—we have known of many manumitted slaves, since his time, much more wealthy than he ever was; three for example, all at the same time, in the reign of the Emperor Claudius: Pallas, Callistus, and Narcissus. But to omit further mention of these men, let us turn to Caius Cæcilius Claudius Isidorus, who, in the consulship of Gallus and Censorinus, upon the sixth day before the calends of February, declared by his will, that though he had suffered great losses through the civil wars, he was still able to leave behind him four thousand one hundred and sixteen slaves, three thousand six hundred pairs of oxen, and two hundred and fifty-seven thousand heads of other kind of cattle, besides, in ready money, sixty millions of sesterces. Upon his funeral, also, he ordered eleven hundred thousand sesterces to be expended. And yet, supposing all these enormous riches to be added together, how small a proportion will they bear to the wealth of Ptolemæus; the person who, according to Varro, when Pompey was on his expedition in the countries adjoining Judæa, entertained eight thousand horsemen at his own expense, and gave a repast to one thousand guests, setting before every one of them a drinking-cup of gold, and changing these vessels at every course! And then, again, how insignificant would his wealth have been by the side of that of Pythius the Bithynian[206]—for I here make no mention of kings. He it was who gave the celebrated plane-tree and vine of gold to King Darius, and who entertained at a banquet the troops of Xerxes, seven hundred and eighty-eight thousand men in all; with a promise of pay and corn for the whole of them during the next five months, on condition that one at least of his five children, who had been drawn for service, should be left to him as the solace of his old age. And yet, let any one compare the wealth of Pythius to that possessed by King Crœsus!
