Maria Antonia, Princess of Bavaria, Electress of Saxony (18 July 1724 – 23 April 1780) was a German princess, composer, singer, harpsichordist and patron of the arts, known particularly for her operas: Il trionfo della fedeltà (“The triumph of fidelity”) and Talestri, regina delle amazoni (“Talestri, queen of the Amazons”).

She left Dresden during the Seven Years' War and took refuge in Prague and Munich, but returned at her husband’s accession to the throne in 1763.

After moving to Dresden she continued her studies with Giovanni Alberto Ristori, Nicola Porpora and Johann Adolph Hasse.

The court of Munich celebrated her birth with a performance of the opera Amadis de Grecia by Pietro Torri.

Shortly after moving to Dresden, she penned the libretto for Hasse’s oratorio, La conversione di Sant’Agostino (1750), in addition to her composing work.

Ultimately, the plot ends happily, with each couple united and war averted, as the Scythians and Amazons manage to peacefully co-exist.

The depiction of the benevolent, thoughtful ruler Talestris coming to be a political leader suggests the possibility that the opera is a semi-autobiographical rendering of Maria Antonia herself.
