Daughter of the Count Palatine of Padolia, beloved by Mazeppa. The count, her father, was very indignant that a mere page should presume to fall in love with his daughter, and had Mazeppa bound to a wild horse and set adrift. As for Theresa, Mazeppa never knew her future history. Theresa was historically not the daughter, but the young wife, of the fiery count. (Byron: Mazeppa.)
