CAUSA XXIX.

It was insinuated to a noble woman that a a certain noble man would seek to marry her.  She agreed to this marriage.  Then a certain non-noble man who was a slave presented himself to her as the noble suitor and took her as his wife.  The first man who had sought her hand came and asked her to marry him.  She complained that she was deceived and wished to marry him.  Therefore it is asked whether the first marriage between them is valid?  Second, if she thought that he was free and soon learned that he was a slave, whether she could immediately leave him?
