Camillo Talamo

Carmela becomes the obsession of the young Count Luigi, heir to the recently deceased's estate, who moves into the decrepit villa nearby. The count is an inveterate womanizer and ends up snatching Carmela from her boyfriend, deceiving her with his lies. Wounded in a duel over another woman, the nobleman is assisted night and day by Carmela, who witnesses a number of moments of delirium in which the man accuses the butler, Giangrande, of an unspecified blunder.

Claudio is married to Cesarina, a frivolous and unfaithful woman. After the death of their only son their marriage is cold. While his wife lives her free life, Claudio is dedicated to the development of sophisticated weapons, elaborating the project of a new cannon; but smitten by the virtuous Jew Rebecca he can not surrender to his feelings because his religion prevents him from getting a divorce.
