The Boule, or parliament-house, possesses a considerable library.
The new constitution provided for a boule whose members were to be recruited by lot from all citizens above thirty; the functions of this body to be exercised by four sections succeeding one another by yearly rotation and serving without pay; all high officials to be chosen by it out of its own members.
In Athens in the sixth prytany of each year the representatives of the Boule asked the Ecclesia whether it was for the welfare of the state that ostracism should take place.
The archons and members of the boule, who certainly received remuneration in 411, and also some minor magistrates, were perhaps paid for the first time by Pericles.
By making effective the powers of the Ecclesia (Popular Assembly) the Boule (Council) and Heliaea, Cleisthenes became the true founder of Athenian democracy.
