for when you were demanding of the cities money for corn, whence was the corn to be procured for you to send to Rome, if you had it not all collected and locked up? Therefore, in the affair of that corn, the first profit of all was that of the corn itself, which had been taken by violence from the cultivators; the next profit was because that very corn which had been procured by you during your three years, you sold not once, but twice; not for one payment, but for two, though it was one and the same lot of corn; once to the cities, for fifteen sesterces a medimnus, a second time to the Roman people, from whom you got eighteen sesterces a medimus for the very same corn.
