Boyet reports to the Princess that the King and his lords, disguised as Russians, will visit the ladies. The Princess tells her ladies that she and they will cover their faces with masks and exchange the gifts sent to them. Each will wear another’s gift. The King and the lords will then mistake the ladies for each other and each lord will vow his love to the wrong lady. Later, when the lords return in their proper dress, the ladies will be able to mock them for their mistakes. All occurs as the Princess plans.

At the end of the year the men may, if they wish, renew their proposals of marriage.
