But, whatever the effects of the metallic prizes of the great campaigns,
these prizes could neither have benefited the members of the nobility as
a whole nor, in the days of comparative peace which had followed the
long epoch of war with wealthy powers, could they be contemplated as a
permanent source of future capital or income. When the representative of
the official caste looked round for modes of fruitful investment which
might increase his revenues, his chances at first sight appeared to be
limited by legal restrictions which expressed the supposed principles of
his class. A Clodian law enacted at the beginning of the Second Punic
War had provided that no senator or senator's son should own a ship of a
burden greater than three hundred amphorae. The intention of the measure
was to prohibit members of the governing class from taking part in
foreign trade, as carriers, as manufacturers, or as participants in the
great business of the contract for corn which placed provincial grain on
the Roman market; and the ships of small tonnage which they were allowed
to retain were intended to furnish them merely with the power of
transporting to a convenient market the produce of their own estates in
Italy.[103] The restriction was not imposed in a self-regarding spirit;
it was odious to the nobility, and, as it was supported by Flaminius,
must have been popular with the masses, who were blind to the fact that
the restriction of a senator's energies to agriculture would be
infinitely more disastrous to the well-being of the average citizen than
the expenditure of those energies in trade. The restriction may have
received the support of the growing merchant class, who were perhaps
pleased to be rid of the competition of powerful rivals, and it
certainly served, externally at least, to mark the distinction between
the man of large industrial enterprises and the man whose official rank
was supported by landed wealth--a distinction which, in the shape of the
contrast drawn between knights and senators, appears at every turn in
