The only notable innovations since the days of Cleisthenes had been the reduction of the archonship to a routine magistracy appointed partly by lot (487), and the rise of the ten elective strategi (generals) as chief executive officers (see Strategus).
The measure by which the archonship was opened to the third and (practically) to the fourth class of citizens (the Zeugitae and Thetes) may also be due to Pericles; the date is now known to be 457 (Const.
In the archonship of Polyzelus (367-366), after the death of his father, in his eighteenth year, he came to Athens, and having joined Plato spent twenty years with him.

From this widely accepted belief arose the almost certainly false statement that Peisistratus took part in Solon's successful war against Megara, which necessarily took place before Solon's archonship (probably in 600 B.C.).
There can, on these assumptions, be no doubt that, from the early years of the 5th century B.C., the archonship was of practically no importance.
No doubt, however, he went on writing and rewriting well into the last period of his life; for example, the recently discovered 'Ath i valwv 7roXtreia mentions on the one hand (c. 54) the archonship of Cephisophon (329-328), on the other hand (c. 46) triremes and quadriremes but without quinqueremes, which first appeared at Athens in 325-324; and as it mentions nothing later it probably received its final touches between 329 and 324.
He was born in the 99th Olympiad in the archonship at Athens of Diotrephes (384-383), three years before Demosthenes.
In 487 B.C., however, the introduction of the lot as a part of the process of filling the archonship (see Archon) began to undermine its ability.
