The Beautiful Deception - S2-E3
Factual error: Cardinal della Rovere says he wishes to join the Dominican Order instead of the Capuchin Order because the former's rule is stricter. In actual fact, the Capuchin rule is one of the strictest of all Roman Catholic orders, something which della Rovere would certainly have known.
Chosen answer: The Borgias arranged Lucrezia's marriage to Giovanni Sforza for their own political gain. When Giovanni was no longer considered useful to them politically, they sought to end the marriage. Eventually, Giovanni reluctantly agreed to admit to impotence in exchange for keeping Lucrezia's dowry, which normally would have reverted back to the family in the event of an annulment. Divorce was rare at that time, and being unable to consummate a marriage was one grounds for an annulment. In the series, when the Borgias convene the College of Cardinals to have Giovanni prove his potency by performing with two overweight and unattractive prostitutes, he refuses because he is humiliated. The historical facts are mostly accurate, though the part about the prostitutes is probably fiction.
