If then the legislator ought to take care that the bodies of the children are as perfect as possible, his first attention ought to be given to matrimony; at what time and in what situation it is proper that the citizens should engage in the nuptial contract. Now, with respect to this alliance, the legislator ought both to consider the parties and their time of life, that they may grow old at the same part of time, and that their bodily powers may not be different; that is to say, the man being able to have children, but the woman too old to bear them; or, on the contrary, the woman be young enough to produce children, but the man too old to be a father; for from such a situation discords and disputes continually arise. In the next place, with respect to the succession of children, there ought not to be too great an interval of time between them and their parents; for when there is, the parent can receive no benefit from his child's affection, or the child any advantage from his father's protection; [1335a] neither should the difference in years be too little, as great inconveniences may arise from it; as it prevents that proper reverence being shown to a father by a boy who considers him as nearly his equal in age, and also from the disputes it occasions in the economy of the family. But, to return from this digression, care ought to be taken that the bodies of the children may be such as will answer the expectations of the legislator; this also will be affected by the same means. Since season for the production of children is determined (not exactly, but to speak in general), namely, for the man till seventy years, and the woman till fifty, the entering into the marriage state, as far as time is concerned, should be regulated by these periods. It is extremely bad for the children when the father is too young; for in all animals whatsoever the parts of the young are imperfect, and are more likely to be productive of females than males, and diminutive also in size; the same thing of course necessarily holds true in men; as a proof of this you may see in those cities where the men and women usually marry very young, the people in general are very small and ill framed; in child-birth also the women suffer more, and many of them die. And thus some persons tell us the oracle of Traezenium should be explained, as if it referred to the many women who were destroyed by too early marriages, and not their gathering their fruits too soon. It is also conducive to temperance not to marry too soon; for women who do so are apt to be intemperate. It also prevents the bodies of men from acquiring their full size if they marry before their growth is completed; for this is the determinate period, which prevents any further increase; for which reason the proper time for a woman to marry is eighteen, for a man thirty-seven, a little more or less; for when they marry at that time their bodies are in perfection, and they will
