Along with this new schedule of taxable capital, a new distribution of the citizens now took place into certain bodies called Symmories. As far as we can make out, on a very obscure subject, it seems that these Symmories were twenty in number, two to each tribe; that each contained sixty citizens, thus making one thousand two hundred in all; that these one thousand two hundred were the wealthiest citizens of the schedule,—containing, perhaps, the two first out of the four classes enrolled. Among these one thousand two hundred, however, the three hundred wealthiest stood out as a separate body; thirty from each tribe. These three hundred were the wealthiest men in the city, and were called “the leaders or chiefs of the Symmories.” The three hundred and the twelve hundred corresponded, speaking roughly, to the old Solonian classes of Pentakosiomedimni and Hippeis; of which latter class there had also been twelve hundred, at the beginning of the Peloponnesian war.[241] The liturgies, or burdensome and costly offices, were discharged principally by the Three Hundred, but partly also by the Twelve Hundred. It would seem that the former was a body essentially fluctuating, and that after a man had been in it for some time, discharging the burdens belonging to it, the Stratêgi or Generals suffered him to be mingled with the Twelve Hundred, and promoted one of the latter body to take his place in the Three Hundred. As between man and man, too, the Attic law always admitted the process called Antidosis, or Exchange of Property. Any citizen who believed himself to have been overcharged with costly liturgies, and that another citizen, as rich or richer than himself, had not borne his fair share,—might, if saddled with a new liturgy, require the other to undertake it in his place; and in case of refusal, might tender to him an exchange of properties, under an engagement that he would undertake the new charge, if the property of the other were made over to him.
