Tarquinia Molza (1 November 1542 – 8 August 1617) was an Italian singer, poet, conductor, composer, and natural philosopher.
Trained in both distinctly male and female singing styles, her contributions helped combine them into the madrigal of the late Renaissance.
[8] She studied with the scientist John Politiano and the poet Francis Patrizio, and learned astronomy from the mathematician Antony Guarini.
Because she was widowed, she was recruited to become the lady-in-waiting to Duchess Margherita Gonzaga d'Este in 1583 and moved to Ferrara, where she became a famous performer, conductor, and composer.
Molza was dismissed from her position in 1589 and returned to Mantua when she was accused of having an affair with Flemish composer Giaches de Wert.
