But the condition of society pictured by Seneca and Petronius is that of the first century of the Christian era and might not be taken to represent the condition of affairs in the second century B.C., had we not some data which go to prove the concentration of property, the disparity between classes, and the depopulation of Italy within the same century as the Gracchi. Cicero was not considered one of the richest men in Rome, yet he possessed many villas, and he has himself told us that one of them cost him 3,500,000 sesterces, about $147,000.[11] Cornelia, the mother of the Gracchi, had a country residence in the vicinity of Micenum which cost[12] 75,000 drachmae ($14,000); Lucullus some years afterwards bought it for 500,200 drachmae ($100,040). According to Cicero,[13] Crassus had a fortune of 100,000,000 sesterces ($4,200,000). This does not astonish us when we see upon the _via Appia,_ near the ruins of the circus of Caracalla and but a short distance from the Catacombs of St. Sebastian and the fountain of Aegeria, the still important remains of the tomb of Caecilia Metella, daughter of Metellus Creticus and wife of the tribune Crassus, as the inscription testifies. It is a vast "funereal fortress" constructed of precious marble, and which gives us the first example of the luxury afterwards so common among the Romans. Then, too, we remember that Crassus was wont to say that no one was rich who was not able to support an army with his revenues, to raise six legions and a great number of auxiliaries, both infantry and cavalry.[14] Pliny confirms this statement concerning Crassus, but adds that Sulla was even richer.[15] Plutarch gives us fuller details and also explains the origin of the colossal fortune of Crassus. According to him Crassus had 300 talents ($345,000), with which to commence. Upon his departure for the Parthian war in which he lost his life, he made an inventory of his property and found that he was possessed of 7,100 talents, $8,165,000, double what Cicero attributes to him. How did Crassus increase his fortune so enormously? Plutarch says that he bought the property confiscated by Sulla at a very low figure. Then, he had a great number of slaves distinguished for their talents; lecturers, writers, bankers, business men, physicians, and hotel-keepers, who turned over to him the benefits which they realized in their diverse industries. Moreover, he had among his slaves 500 masons and architects. Rome was built almost entirely of wood and the houses were very high, consequently fires were frequent and destructive. As soon as a fire broke out, Crassus hastened to the place with his throng of slaves, bought the now burning buildings--as well as those threatened--at a song, and then set his slaves to work extinguishing the fires. By this means he had become possessed of a large[16] part of Rome.
