Olimpia Aldobrandini (1623-1681) was the great niece and sole heir of Pope Clement VII Aldobrandi and the Aldobrandini fortune. She bore three children to her husband Camillo (1622-1666), nephew to Pope Innocent X. Pope Innocent X gave the cardinalate to Camillo, however, he renounced it in 1647 in order to marry Olimpia. During the mid 1600s Camillo and Olimpia began collecting works that would form the great Pamphili collection that included Titian’s Salome with the Head of John the Baptist, which was in their possession between 1638 and 1682. Other works such as Rest on the Flight into Egypt by Caravaggio, Portrait of Innocent X by Velazquez, Landscape with Figures Dancing by Claude Lorrain, Innocent X by Gian Lorenzo Bernini, and more.
