Gustav IV Adolf of Sweden
Tintomara is said to have been inspired by the daughter of Giovanna Bassi, Johanna Fredrika (1787–1810), who was presumed to be fathered by Count Adolf Fredrik Munck af Fulkila. By persistent rumors, the count was said to be the true father of Gustav IV Adolf of Sweden; Bassi's daughter was said to have a strong resemblance to the King, who might have been her half-brother.
