Theomnestus and Apollodorus Against Neaera (92)

These are not events of long ago of which you might be ignorant.

However, although the laws regarding citizenship and the steps that must be taken before one may become an Athenian are so admirably and so securely established, there is yet another law which has been enacted in addition to all these, and this law is of paramount validity; such great precautions have the people taken in the interest of themselves and of the gods, to the end that the sacrifices on the state’s behalf may be offered in conformity with religious usage. For in the case of all those whom the Athenian people may make citizens, the law expressly forbids that they should be eligible to the office of the nine archons or to hold any priesthood; but their descendants are allowed by the people to share in all civic rights, though the proviso is added: if they are born from an Athenian woman who was betrothed according to the law.
