Two Knights (Due Cavalieri) by Giorgio de Chirico
This cover of the April 1905 issue of Musica magazine shows the famous soprano Lina Cavalieri, who was the most photographed woman in the Belle Epoque. She was a good friend of Enrico Caruso. A beautiful woman and an exciting life story. Was able to acquire some of these rare, preserved editions.
Lina Cavalieri, Postcard, 1900.
Lina Cavalieri was an Italian operatic soprano known for her great beauty, and one of the most frequently photographed personalities of her time.
On December 5th 1906, Lina Cavalieri gave tenor Enrico Caruso a passionate kiss in front of an astounded audience, caught completely by surprise by the opera singer’s intense gesture.
After that, “the most beautiful woman in the world”, as fans called her, also became “the kissing primadonna”: that “coup de théâtre” on the stage of New York’s Metropolitan Opera House made Umberto Giordano’s “Fedora” simply unforgettable, and brought Cavalieri great luck in her career. (x)
