Histories

They say that no one has ever yet killed his father or mother; when such a thing has been done, it always turns out on inquest that the doer is shown to be a changeling or the fruit of adultery; for it is not to be believed (say they) that a son should kill his true parent.

Furthermore, of what they may not do, they may not speak, either. They hold lying to be the most disgraceful thing of all and next to that debt; for which they have many other reasons, but this in particular: it is inevitable (so they say) that the debtor also speak some falsehood. The citizen who has leprosy or the white sickness may not come into town or mingle with other Persians. They say that he is so afflicted because he has sinned in some way against the sun.

Every stranger who gets such a disease, many drive out of the country; and they do the same to white doves, for the reason given. Rivers they especially revere; they will neither urinate nor spit nor wash their hands in them, nor let anyone else do so.
