Eleonora is the Italian form of Eleanor — possibly from the Provençal alia Aenor ("the other Aenor"). **Eleonora di Toledo (1522-1562)** — **Spanish-born Duchess of Florence, wife of Cosimo I de' Medici, subject of Bronzino's most famous portrait** (1545); she negotiated diplomatic alliances, regulated Florence's finances, and bore 11 children. **Eleonora d'Arborea (1347-1404)** — judge-queen of Sardinia whose *Carta de Logu* legal code remained in force on the island for 400 years. **Eleonora Duse (1858-1924)** — among the greatest Italian actresses of the late 19th century.
Subject of Gabrielle Langdon's *Medici Women: Portraits of Power* (2007).
Eleonora reduces to seven — the number of Italian Renaissance duchess.
