Elisa d'Este

Elisa d'Este (1337 – 12 August 1402) was a Ferrarese noblewoman, daughter of Obizzo III d'Este, lord of Ferrara, and Lippa Ariosti. In 1350 she married Guido III da Polenta, who ruled Ravenna for thirty peaceful years after 1359 and was named the city's papal vicar in 1364.

Her daughters included Leta and Beatrice. In 1389 Guido was seized and imprisoned by his own sons and died in their custody that December, while Elisa lived on until 1402.
