Portrait of a Woman, probably Isabella d'Este, c.1500 (terracotta)

Isabella d'Este (18 May 1474 – 13 February 1539) was Marchesa of Mantua and one of the leading women of the Italian Renaissance as a major cultural and political figure. She was a patron of the arts as well as a leader of fashion, whose innovative style of dressing was copied by women throughout Italy and at the French court. The poet Ariosto labeled her as the "liberal and magnanimous Isabella", while author Matteo Bandello described her as having been "supreme among women". Diplomat Niccolò da Correggio went even further by hailing her as "The First Lady of the world".
