Prostitution, extramarital affairs, homosexuality, incest—the ancient Romans were remarkably uninhibited. Monogamy was the only requirement. Originally, living together ‘with affection’ sufficed, but under Roman law the idea of a “legalized family” emerged, sealed by a public ceremony that recognized the couple’s duties and privileges in society.
The ritual formula was “Ubi tu Gaius, ibi ego Gaia” (“Where you are Gaius, there I am Gaia”), whereby the bride moved from her father’s authority into her husband’s. The jurist Modestinus called it “a partnership for life,” and it became a legal obligation. On the wedding day—chosen by an augury—the groom would present fresh bread to his bride, and she would wear a white dress, an orange veil, and a wreath of flowers.
