With the development of the patriarchal system and the custom of marriage by capture or purchase, woman came to be regarded as a part of man's property, and as inviolate as any other of his possessions. Under these circumstances virginity came to be more and more of an asset, since no man wished his property to be denied by the touch of another. Elaborate methods for the preservation of chastity both before and after marriage were developed, and in many instances went so far as to consider a woman defiled if she were accidentally touched by any other man than her husband. Here we have once more the working of sympathetic magic, where the slightest contact works contamination. We have in other connections alluded to the seclusion of young girls in Korea, among the Hindus, among the North American Indians, and in the South Seas. One of the most beautiful examples of this custom is found in New Britain. From puberty until marriage the native girls are confined in houses with a bundle of dried grass across the entrance to show that the house is strictly taboo. The interior of these houses is divided into cells or cages in each of which a girl is confined. No light and little or no air enters, and the atmosphere is hot and stifling. The seclusion of women after marriage is common among many peoples. In the form in which it affected western civilization it probably originated among the Persians or some other people of central Asia, and spread to the Arabs and Mohammedans. That it did not originate with the Arabs is attested by students of their culture. It was common among the Greeks, whose wives were secluded from other men than their husbands. In modern Korea it is not even proper to ask after the women of the family. Women have been put to death in that country when strange men have accidentally touched their hands.[36, p.341] The saddest outcome of the idea of woman as property was the status of widows. In uncivilized society a widow is considered dangerous because the ghost of her husband is supposed to cling to her. Hence she must be slain that his spirit may depart in peace with her, as well as with the weapons and other possessions which are buried with him or burned upon his funeral pyre. The Marathi proverb to the effect that "the husband is the life of the woman" thus becomes literally true.
