Legally more enslaved than the Greek woman, the Roman is more deeply integrated in society; at home she sits in the atrium, which is the center of thedomicile, rather than being relegated to the gynaeceum; it is she who presides over the slaves' work; she oversees the children's education, and her influence on them often extends to an advanced age; she shares her husband's work and his concerns, she is considered a co owner of his property; the marriage formula 'Ubi tu Gaius, ego Gaia' is not an empty formula; the matron is calleddomina; she is mistress of the home, associate in religion, not a slave but man's companion; the tie that unites her to him is so sacred that in five centuries not one divorce is recorded.
