As soon as the Four Hundred found themselves formally installed in the senate-house, they divided themselves by lot into separate prytanies,—probably ten in number, consisting of forty members each, like the former senate of Five Hundred, in order that the distribution of the year to which the people were accustomed might not be disturbed,—and then solemnized their installation by prayer and sacrifice. They put to death some political enemies, though not many: they farther imprisoned and banished others, and made large changes in the administration of affairs, carrying everything with a strictness and rigor unknown under the old constitution.[55] It seems to have been proposed among them to pass a vote of restoration to all persons under sentence of exile. But this was rejected by the majority in order that Alkibiadês might not be among the number; nor did they think it expedient, notwithstanding, to pass the law, reserving him as a special exception. [55] Thucyd. viii, 70. I imagine that this must be the meaning of the words τὰ τε ἄλλα ἔνεμον κατὰ κράτος τὴν πόλιν. They farther despatched a messenger to Agis at Dekeleia, intimating their wish to treat for peace; which, they affirmed, he ought to be ready to grant to them, now that “the faithless Demos” was put down. Agis, however, not believing that the Athenian people would thus submit to be deprived of their liberty, anticipated that intestine dissension would certainly break out, or at least that some portion of the Long Walls would be found unguarded, should a foreign army appear. While therefore he declined the overtures for peace, he at the same time sent for reinforcements out of Peloponnesus, and marched with a considerable army, in addition to his own garrison, up to the very walls of Athens. But he found the ramparts carefully manned: no commotion took place within: even a sally was made, in which some advantage was gained over him. He therefore speedily retired, sending back his newly-arrived reinforcements to Peloponnesus; while the Four Hundred, on renewing their advances to him for peace, now found themselves much better received, and were even encouraged to despatch envoys to Sparta itself.[56] [56] Thucyd. viii, 71.
