Did the poorer citizens only receive the distribution? It was calculated, to be sure, chiefly for their benefit; but it appears from a passage in Cicero that the rich might also take their portion, and that it was esteemed no reproach in them to apply for it. To whom was the corn given—whether only to heads of families, or to every man, woman, and child? The portion every month was five modii to each (about five-sixths of a bushel). This was too little for a family, and too much for an individual. A very accurate antiquarian therefore infers that it was given to every man of full years, but he allows the matter to be uncertain. Was it strictly inquired whether the claimant lived within the precincts of Rome, or was it sufficient that he presented himself at the monthly distribution? This last seems more probable.​[86] Were there no false claimants? We are told that Cæsar struck off at once 170,000, who had crept in without a just title; and it is very little probable that he remedied all abuses. But, lastly, what proportion of slaves must we assign to these citizens? This is the most material question, and the most uncertain. It is very doubtful whether Athens can be established as a rule for Rome. Perhaps the Athenians had more slaves, because they employed them in manufactures, for which a capital city like Rome seems not so proper. Perhaps, on the other hand, the Romans had more slaves, on account of their superior luxury and riches. There were exact bills of mortality kept at Rome; but no ancient author has given us the number of burials, except Suetonius, who tells us that in one season there were 30,000 dead carried into the temple of Libetina; but this was during a plague, which can afford no certain foundation for any inference. The public corn, though distributed only to 200,000 citizens, affected very considerably the whole agriculture of Italy, a fact no way reconcilable to some modern exaggerations with regard to the inhabitants of that country. The best ground of conjecture I can find concerning the greatness of ancient Rome is this: We are told by Herodian that Antioch and Alexandria were very little inferior to Rome. It appears from Diodorus Siculus that one straight street of Alexandria, reaching from port to port, was five miles long; and as Alexandria was much more extended in length than breadth, it seems to have been a city nearly of the bulk of Paris,​[87] and Rome might be about the size of London. There lived in Alexandria, in Diodorus Siculus’s time, 300,000 free people, comprehending, I suppose, women and children.​[88] But what number of slaves? Had we any just ground to fix these at an equal number with the free inhabitants, it would favour the foregoing calculation.
