The author of the Athenaion Politeia, whether Aristotle or a pupil of his, said that in 462/1 Ephialtes took from the Areopagite Council ‘the additional functions (epitheta), through which it had guardianship of the constitution’, and gave some of these to the council of five hundred but others to the assembly and the courts (25.2). The author did not specify the functions given to the recipient bodies; the reason may well be that he did not know what they were. But many readers have supposed that in calling those functions ‘additional’ the author followed the view taken by the reformers of 462/1. This explanation suggests that the author drew, directly or indirectly, on sources contemporary with the reform.
