Eleonora d'Este (1515–1575)

She was brought up in Ferrara and her mother died when she was four – her father had two more children with Laura Dianti.

She became a nun at the Corpus Domini Monastery and was buried there alongside her mother and other members of her family.

In 1543, Girolamo Scotto of Venice published a collection of 43 religious motets under the title Musica quinque vocum motetta materna lingua vocata.

[1] Laurie Stras, professor of music at Southampton University, has argued that Leonora may have been the composer.

[2] Leonora was triply disqualified from being named in those days: being a woman, and a princess, and a nun.
