Claudia Colla (died 1611), was the ducal mistress of the sovereign Ranuccio I Farnese, Duke of Parma, by whom she was murdered.
Colla belonged to the Parmesan merchant class. In 1599, her ducal lover Farnese married Margherita Aldobrandini. After a decade of childless marriage, Farnese accused Claudia Colla and her mother Elena for having caused the lack of offspring by the use of sorcery.[1] The accusation of sorcery was unusual for someone of her class.[2] She was judged guilty and sentenced to be executed by burning.
