Is the opera Aida historically correct?
Look at Aida and Nine Readings by Ralph P. Locke, you’ll find the article in the 2006 edition of Nineteenth Century Music Reviews. He gives views on the to this question. I think it is quite correct but maybe a little biased as Verdi is an Italian patriot and in the opera, ancient Egypt is analogic to Austro-Hungary and Napoleonic France, two imperial countries that took over Italy ( which can be compared to the Ethiopia in ‘Aida’).
