We know that the aged sexagenarians were called depontani, because they were forbidden the bridges over which they must go to the place of voting. (Festus, under the word sexagenarius, p. 834.—Cicero, Pro S. Roscio Amerino, 35.)
80,000 men in condition to carry arms represent, according to the statistics of the present time, fifty-five hundredths of the male part of the population, say 145,000 men, and for the two sexes, supposing them equal in number, 290,000 souls. In fact, in France, in a hundred inhabitants, there are 35 who have not passed the age of seventeen, 55 aged from seventeen to sixty years, and 10 of more than sixty.
In support of the above calculation, Dionysius of Halicarnassus relates that in the year 247 of Rome a subscription was made in honour of Horatius Cocles: 300,000 persons, men and women, gave the value of what each might expend in one day for his food. (V. 25.)
As to the number of slaves, we find in another passage of Dionysius of Halicarnassus (IX. 25) that the women, children, slaves, merchants, and artisans amounted to a number triple of that of the citizens.
If, then, the number of citizens in condition to carry arms was 80,000, and the rest of the population equalled three times that number, we should have for the total 4 x 80,000 = 320,000 souls. And, subtracting from this number the 290,000 obtained above, there would remain 30,000 for the slaves and artisans.
Whatever proportion we admit between these two last classes, the result will be that the slaves were at that period not numerous.

[52] “Within the town, the buildings were not allowed to approach the ramparts, which they now ordinarily touch, and outside a space extended which it was forbidden to cultivate. To all this space, which it was not permitted to inhabit or cultivate, the Romans gave the name of Pomœrium. When, in consequence of the increase of the town, the rampart was carried farther out, this consecrated zone on each side was still preserved.” (Titus Livius, I. 44.)
