Focus on Saturn Devouring His Son and explain the Transfer from the Quinta del Sordo.
When Goya went into self-imposed exile in France in 1823, he passed the Quinta del Sordo to his grandson Mariano. After various changes of ownership, the house came into the possession of the Belgian Baron Émile d'Erlanger in 1874. After 70 years on the walls of the Quinta del Sordo, the murals were deteriorating badly and, in order to preserve them, the new owner of the house had them transferred to canvas under the direction of Salvador Martínez Cubells, the chief art restorer at the Museo del Prado. After showing them at the Exposition Universelle of 1878 in Paris, d'Erlanger eventually donated them to the Spanish state. The effects of time on the murals, coupled with the inevitable damage caused by the delicate operation of mounting the crumbling plaster on canvas, meant that most of the murals required restoration work and some detail may have been lost.
