The same thing they say was afterwards prophesied by the Sibyl
concerning the city, in these words:

"The bladder may be dipped, but cannot drown."

XXV. Wishing still further to increase the number of his citizens, he
invited all strangers to come and share equal privileges, and they say
that the words now used, "Come hither all ye peoples," was the
proclamation then used by Theseus, establishing as it were a
commonwealth of all nations. But he did not permit his state to fall
into the disorder which this influx of all kinds of people would
probably have produced, but divided the people into three classes, of
Eupatridae or nobles, Geomori or farmers, Demiurgi or artisans. To the
Eupatridae he assigned the care of religious rites, the supply of
magistrates for the city, and the interpretation of the laws and customs
sacred or profane, yet he placed them on an equality with the other
citizens, thinking that the nobles would always excel in dignity, the
farmers in usefulness, and the artisans in numbers. Aristotle tells us
that he was the first who inclined to democracy, and gave up the title
of king; and Homer seems to confirm this view by speaking of the people
of the Athenians alone of all the states mentioned in his catalogue of
ships. Theseus also struck money with the figure of a bull, either
alluding to the bull of Marathon, or Taurus, Minos' general, or else to
encourage farming among the citizens. Hence they say came the words,
"worth ten," or "worth a hundred oxen." He permanently annexed Megara to
Attica, and set up the famous pillar on the Isthmus, on which he wrote
the distinction between the countries in two trimeter lines, of which
the one looking east says,

"This is not Peloponnesus, but Ionia,"
