It is named after Leopoldo de Gregorio, 1st Marquess of Esquilache, Spanish ambassador to Venice, who bought the work. On his death it passed to Cardinal Gregorio, who in turn left it to Pope Pius VI from the Braschi family, which finally sold it to its present owner in 1842. From 1924 to 1931 it hung in the Pushkin State Museum of Fine Arts before returning to the Hermitage, where it remains.[2]
