The Museo del Prado library, presently installed in the Casón del Buen Retiro, houses an important Old Books Holdings, notably increased the past years thanks to the acquisition of the José María Cervelló library and the Daza-Madrazo family library. The exhibition will show forty books and manuscripts dated between 1500 and 1750, as well as a group of eight paintings from the museum’s collection (Titian, El Greco, Velázquez, etc) which will reveal different connections between the bibliographical fund and the paintings collection.
