Solon (19.2-19.3)

Then he made the upper council a general overseer in the state, and guardian of the laws, thinking that the city with its two councils, riding as it were at double anchor, would be less tossed by the surges, and would keep its populace in greater quiet.

Now most writers say that the council of the Areiopagus, as I have stated, was established by Solon. And their view seems to be strongly supported by the fact that Draco nowhere makes any mention whatsoever of Areiopagites, but always addresses himself to the ephetai in cases of homicide.

Yet Solon’s thirteenth table contains the eighth of his laws recorded in these very words: As many of the disfranchised as were made such before the archonship of Solon, shall be restored to their rights and franchises, except such as were condemned by the Areiopagus, or by the ephetai, or in the prytaneium by the kings, on charges of murder or homicide, or of seeking to establish a tyranny, and were in exile when this law was published.
