The Republic · Rep. 461b–461c

This applies, however, only to those who are within the specified age: after that we allow them to range at will, except that a man may not marry his daughter or his daughter’s daughter, or his mother or his mother’s mother; and women, on the other hand, are prohibited from marrying their sons or fathers, or son’s son or father’s father, and so on in either direction. And we grant all this, accompanying the permission with strict orders to prevent any embryo which may come into being from seeing the light; and if any force a way to the birth, the parents must understand that the offspring of such an union cannot be maintained, and arrange accordingly.
