was always a means of securing her economic independence, and thus of promoting the happiness of her married life. "In this way she was protected from tyrannical conduct upon his part, as well as from the fear of divorce on insufficient grounds. If a divorce took place the husband was required to hand over to the wife all the property she had brought with her as dowry, and she then either returned to her father's home or set up an independent establishment of her own." The divorced woman might marry again if she chose. "Marriage was partly a religious and partly a civil function. The contracting parties frequently invoked the gods, and signed the contract in the presence of the priest. At the same time it was a contract, and in order to be legally valid it had to be drawn up in legal form and attested by a number of witnesses. Like all other legal documents it was carefully dated and registered."--_Idem_, _ibid._, 46, 47, 49, 50. _Cf._ for the forms of contract and ceremony his _Babylonians and Assyrians_, 13-43; also the interesting account of SIMCOX, _Primitive Civilizations_, I, 360-79; her discussion of the similarly advanced domestic relations of the ancient Egyptians, _ibid._, I, 198-225; KOHLER, "Ueber zwei babylonische Rechtsurkunden aus der Zeit Nabonids," _ZVR._, V; and HAUPT, _Die sumerischen Familiengesetze_. Thus, to summarize, it appears in general that the institution of dower takes its rise in two principal sources: either it is derived through the return gift from its exact opposite, the ancient purchase price of the bride; or, as a means of providing in some way for the wife as a member of the new household, it has developed along with free marriage, and stands as an expression of the natural motives and desires upon which the human family rests. Strangely enough, in our own society the marriage portion "has become a purchase sum by means of which a father buys a husband for his daughter."[723] It may be doubted whether the ideas which actuate the modern plutocrat in such a transaction differ essentially from those of the rich savage or barbarian who succeeds in procuring a beautiful or high-born maiden in exchange for his flocks. [723] In "our days, a woman without a marriage portion, unless she has some great natural attractions, runs the risk of being a spinster forever. This state of things naturally grows up in a society where monogamy is prescribed by law, where the adult women outnumber the adult men, where many men never marry, and where married women too often lead an indolent life."--WESTERMARCK, _op. cit._, 416.
