Beatrice Michiel
Beatrice Michiel (died 1613) was a spy in the Ottoman court in service of Venice. She was the sister of a eunuch of the Ottoman sultan (who had been captured and enslaved when he was young), and joined him there as an adult. 

Reportedly, she attempted to influence Safiye Sultan (and through her the sultan) to a policy in favour of the Republic of Venice, and by doing so came in conflict with Esperanza Malchi, who had the opposite intention: the two women once came in to open conflict in front of Safiye.
