The nuptial forms were various, and in the course of centuries underwent manifold alterations. The most solemn nuptials were celebrated before the High Priest, in the presence of at least ten witnesses. At the occasion, the bridal pair, in token of their union, partook together from a cake made of flour, salt and water. As will be noticed, a ceremony is here celebrated, that bears great resemblance to the breaking of the sacramental wafer at the Christian communion. A second form of nuptials consisted in possession. The marriage was considered accomplished if, with the consent of her father or guardian, a woman lived with the chosen man a whole year under one roof. A third form of nuptials was a sort of mutual purchase, both sides exchanging coins, and the promise to be man and wife. Already at the time of Cicero[19] free divorce for both sides was generally established; it was even debated whether the announcement of the divorce was necessary. The "lex Julia de adulteriis," however, prescribed that the divorce was to be solemnly proclaimed. This decree was made for the reason that women, who committed adultery, and were summoned to answer the charge, often claimed to have been divorced. Justinian, the Christian[20] forbade free divorce, unless both sides desired to retire to a monastery. His successor, Justinian II, however, found himself obliged to allow it again. With the growing power and rising wealth of Rome, mad-brained vices and excesses took the place of the former severity of manners. Rome became the center from which debauchery, riotous luxury and sensuous refinements radiated over the whole of the then civilized world. The excesses took--especially during the time of the Emperors, and, to a great extent, through the Emperors themselves--forms that only insanity could suggest. Men and women vied with one another in vice. The number of houses of prostitution became ever larger, and, hand in hand with these, the "Greek love" (pederasty) spread itself ever more among the male population. At times, the number of young men in Rome who prostituted themselves was larger than that of the female prostitutes. "The hetairae appeared, surrounded by their admirers, in great pomp on the streets, promenades, the circus and theatres, often carried by negroes upon litters, where, holding a mirror in their hands, and sparkling with ornaments and precious stones, they lay outstretched, nude, fan-carrying slaves standing by them, and surrounded by a swarm of boys, eunuchs and flute-players; grotesque dwarfs closed the procession."
