Excerpts from Books and Wikipedia
Oil on canvas at Museo del Prado, Madrid;
"He was guarded, and although letters and writings survive, little is known about his thoughts. He suffered a severe and undiagnosed illness in 1793 which left him deaf, after which his work became progressively darker and pessimistic. . . . In 1807, Napoleon led the French army into the Peninsular War against Spain. Goya remained in Madrid during the war, which seems to have affected him deeply. Although he did not speak his thoughts in public, they can be inferred from his Disasters of War series of prints (although published 35 years after his death) and his 1814 paintings The Second of May 1808 and The Third of May 1808. Other works from his mid-period include the Caprichos and Los Disparates etching series, and a wide variety of paintings concerned with insanity, mental asylums, witches, fantastical creatures and religious and political corruption, all of which suggest that he feared for both his country's fate and his own mental and physical health."
