The third collaboration of one Wolfgang Amadeus Mozart and Lorenzo da Ponte, Così fan tutte (roughly translated as "Thus do all [women]" or, more idiomatically, "They [women] are all like that") is an Opera buffa, with catchy tunes, a subverted Love Dodecahedron and a very Warped Aesop by today's standards. The plot was allegedly based on a story told to the Austrian Emperor, who allegedly requested an opera based on it.
