(M322) Marriage is the bond which unites the different members of the family. The married pair, their children, slaves, and adjuncts, one side or the other, constitute the family unit. The Sumerian laws presuppose marriage; but, so far as known, merely attached penalties to repudiation of the wedded ties. The Code is very full and explicit and forms the basis of all our knowledge. The contemporary documents extend it in some particulars. In Assyrian times we know little or nothing about the laws concerning marriage. In later Babylonian times very little is known until the Persian period, when we have many illustrations. But what we know, or can gather from scattered hints, makes it clear that the state of things represented in the Code remained practically unchanged for the whole period. (M323) The Code is explicit that a woman was not a wife without “bonds.”(257) This was a marriage-contract; of which the essentials were that the names of the parties and their lineage were given, the proper consents obtained and the declaration of the man that he has taken so-and-so to wife inserted. As a rule, stringent penalties are set down for a repudiation of the marriage-tie. In these bonds a man might be required to insert the clause that his wife was not to be held responsible for any debts he might have incurred before marriage. The Code enacts that such a clause shall be held to act both ways; if it is inserted, then the man shall not be liable for his wife’s debts before marriage.(258) But, if no such bond existed, the wedded pair were one body as far as liability for debt was concerned, by whichever it had been contracted and, in spite of such a bond, both were liable together for all debts contracted after marriage. (M324) The family relationship was of primary importance. Whatever may be said about traces of matriarchy in Babylonia, we have no legal documents which recognize the institution. The father is the head of the family and possesses full power over his wife and family. But the woman is not in that degraded condition in which marriage by capture, or purchase, left her. She was a man’s inferior in some respects, but his helper and an honorable wife.
