Coëmptio
Properly “a joint taking,” so “a joint purchase.”
One of the three forms of marriage among the Romans. It was so called from the fiction of a
purchase supposed to take place on the occasion. In the presence of five witnesses and a
libripens, or holder of the balance, the bridegroom struck the balance
with a bronze coin, which he handed to the father or guardian of the bride. At the same time
he asked her whether she would be his wife, and she, in turn, asked him whether he would be
her husband. See
Matrimonium.
