In 'AΘΠ. 22. I Aristotle made the judgement that Cleisthenes' reform gave a constitution to Athens far more democratic than Solon's, and to prove it he marked as Cleisthenic the law about ostracism. As the ostracism was considered a typically democratic institution, it was both persuasive and credible to connect Cleisthenes with a measure so admirably symptomatic of the adjudged new order.
