The Athenian Constitution

Ancient accounts of Aristotle credit him with 170 Constitutions of various states; it is widely assumed that these were research for the Politics and that many of them were written or drafted by his students. Athens however was a particularly important state and where Aristotle was living at the time; it is plausible that even if students did the others Aristotle did that one himself and possible that it was intended as a model for the rest.
