For an adult hard-working slave Cato (c.

56) reckons fifty-one -modii-of wheat as the annual consumption.

These data enable any one to answer for himself the question whether a Roman family could or could not subsist on the produce of a -heredium-.

The attempted proof to the contrary is based on the ground that the slave of later times subsisted more exclusively on corn than the free farmer of the earlier epoch, and that the assumption of a fivefold return is one too low for this earlier epoch; both assumptions are probably correct, but for both there is a limit.

Doubtless the subsidiary produce yielded by the arable land itself and by the common pasture, such as figs, vegetables, milk, flesh (especially as derived from the old and zealously pursued rearing of swine), and the like, are specially to be taken into account for the older period; but the older Roman pastoral husbandry, though not unimportant, was withal of subordinate importance, and the chief subsistence of the people was always notoriously grain.
