The frequency of remarriage among the elite was high. Speedy remarriage was not unusual, and perhaps even customary, for aristocratic Romans after the death of a spouse. While no formal waiting period was dictated for a widower, it was customary for a woman to remain in mourning for ten months before remarrying. The duration may allow for pregnancy: if a woman had become pregnant just before her husband's death, the period of ten months ensures that no question of paternity, which might affect the child's social status and inheritance, would attach to the birth. No law prohibited pregnant women from marrying, and there are well-known instances: Augustus married Livia when she was carrying her former husband's child, and the College of Pontiffs ruled that it was permissible as long as the child's father was determined first. Livia's previous husband even attended the wedding.
