Indeed no relationship was traced through the female line; and while marriage was prohibited with any relative who bore the paternal name, there were no restrictions as to unions with those on the mother's side. Marriage was forbidden between a man and his sister-in-law, the widow of his brother, his step-mother, and the sisters-in-law, aunts, and sisters of his mother. Though polygamy was apparently never approved by the Mayans, they repudiated their wives on the most frivolous pretexts, forming a series of new unions. This fickleness seems to have developed a shrewishness among Mayan women, who, usually docile and obedient, avenged themselves upon their husbands for the least infidelity by personal violence, scratching their faces and tearing out their hair. After all, women are much of a muchness all over the world; but, apart from these very natural outbursts of passion, the Mayan women really appear to have been model wives and mothers and to have devoted considerably more attention to the education of the girls than the fathers did to that of the boys. Mayan women do not appear to have taken part in the sacrifices at the temples, whether of human victims or otherwise. The ceremonial dances, too, which appear to have often been of an indecent character, were never attended by them. Indeed it appears that the sexes rarely if ever danced together. The Mayans were passionately fond of dancing, which was of two kinds: the sacred dances at the temples and the public dances on occasions of festival or ceremony. One dance only, called _Naual_, there was which was danced by men and women together. Otherwise the women danced separately from the men, as they ate separately from them. The Mayan women indeed seem to have borne themselves modestly in every way, and drunkenness, the greatest vice of the men, was almost unknown among them.
