The concubine was usually a slave who had been bought by the bridegroom. Occasionally, by agreement with the parents, the wife herself was in much the same position. Thus Dagil-ili, who married the daughter of a lady named Khammâ, gave the mother one and a half manehs of silver and a slave worth half a maneh, and agreed that if he married another wife he would give her daughter a maneh and send her back to her old home. Here the husband practically buys his wife, though even so the law obliged him to divorce her if he married again, and also fined him for doing so. Khammâ was apparently in financial difficulties, and consequently, instead of furnishing her daughter with a dowry, received money from the bridegroom. It was a private arrangement, and utterly opposed to the usual custom. The parents had, however, the power of selling their children before they came of age, and where the parents were dead, the same power was possessed—at any rate in Assyria—by a brother in the case of a sister. Doubtless the power was restricted by law, but the instances in which we hear of its being exercised are so rare that we do not know what these restrictions were. Nor do we know the reasons which were considered sufficient to justify divorce. The language of the early laws would seem to imply that originally it was quite enough to pronounce the words: “Thou art not my wife,” “Thou art not my husband.” But the loss of the wife’s dowry and the penalties attached to divorce must have tended to check it on the part of the husband, except in exceptional circumstances. Perhaps want of children was held to be a sufficient pretext for it; certainly adultery must have been so. Another cause of divorce was a legal one: a second marriage invalidated the first, if the first wife was still alive. This is a very astonishing fact in a country where polygamy was allowed. It proves that polygamy was greatly restricted in practice, and that the tendency of the law was to forbid it altogether. Among the multitudinous contracts of the second Babylonian empire it is difficult to find any which show that a man had two legitimate wives living at one and the same time. The high position of the mother of the family, her independence and commercial equality with her husband, were all against it. It is only where the wife is a bought slave that polygamy can flourish.
