Revealing the African Presence: Portrait of Maria Salviati

"The origin of the project [Revealing the African Presence in Renaissance Europe] was research undertaken in 2000 in response to a query as to the museum's position on the conflicting claims concerning the identity of the child in the Walters' [Walters Museum] painting by Jacopo Pontormo, then called Portrait of Maria Salviati and a Child, datable to ca. 1539. Formulating the wider issues from the perspective of her identity has informed the current exhibition project."
