Dressed as a French peasant boy, Livietta, with her friend Fluvia, plans to lure Tracollo into a trap and punish him because he has robbed Livietta's brother and almost killed him. As Tracollo and his servant Faccenda, disguised as a pregnant Polish woman and a beggar, approach the women, Livietta pretends to be just waking up. She catches Tracollo trying to steal Fulvia s jewelry. Livietta reveals herself and is determined to have Tracollo arrested, whereupon he pleads for mercy. He attempts to calm Livietta down and promises to marry her. Although this is Livietta's greatest wish, she turns him down.
Tracollo has disguised himself as an astrologer and pretends to be deranged in order to soften Livietta's heart after all. To test his supposed unsoundness of mind, Livietta acts the part of one who will soon die. Tracollo proves to be very concerned at this new set of circumstances; he stirs Livietta in such a way, that she leaves off all deception. Both swear to marry, swear eternal love and faithfulness.
'Livietta and Tracollo' counts among the most popular intermezzi of the 18th century and was performed on numerous Italian stages and in other European countries for over 20 years. The production of the Intermezzo, adapted in 1963 by Wolf Ebermann and Manfred Koerth, formed the basis for the performances at the Chamber Opera Vienna (1975), the Schwetzinger Festival (1978) and at the Berlin Chamber Opera (1985).
