"[2] A committee of 10 probouloi was appointed in Athens in 413 BC after the failure of the Sicilian Expedition.
[1] The committee seems to have taken on duties from both the boule and the prytaneis,[1] and they were granted the ability to bypass the ecclesia in order to expedite the war effort.
[3] The probouloi also played a role in the Athenian coup of 411 BC, which established the short-lived oligarchy of the Four Hundred.
[6] Aristotle discusses the probouloi in his Politics, believing the committee to be undemocratic and oligarchical.
[4] A proboulos appears as an antagonist in Aristophanes' comedy Lysistrata, engaging in a debate with the titular protagonist and going on a tirade against her when he loses.
