Philo: The Special Laws, II

VIII. (32) But in the case of those persons who have vowed not merely their own property or some part of it, but also their own selves, the law has affixed a price to their vows, not having a regard to their beauty, or their importance, or to any thing of that kind, but with reference to the number of the individuals separating the men from the women, and the infants from those who are full grown. (33) For the law Ordains

that from twenty years of age to sixty the price of a man shall be two hundred drachmas of solid silver money, and of a woman a hundred and twenty drachmas. And from five years of age to twenty, the price of a male child is eighty, and of a female child forty drachmas. And from infancy to five years old, the price of a male is twenty; of a female child, twelve Drachmas.

And in the case of men who have lived beyond sixty years of age, the ransom of the old men is sixty, and of the old women forty drachmas. (34) And the law has regulated this ransom with reference to the same age both in men and women on account of three most important considerations. First of all, because the importance of their vow is equal and similar, whether it be made by a person of great or of little importance. Secondly, because it is fitting that those who have made a vow should not be exposed to the treatment of slaves; for they are valued at a high or at a low price, according to the good condition and beauty of their bodies, or the contrary. Thirdly, which, indeed, is the most important consideration of all, because inequality is valued among men, but equality is honoured by God.
