Tivoli Opera[1] (established 1882, closed 1886) was Norway's first permanent opera stage, located in the converted banquet hall of Tivoli in Oslo.
The opera was nicknamed Mattis & Moe and was thus, unusually for the time, led by two women.
The artistic director was first the Italian Paolo Sperati, later the young Hjalmar Meissner.
Several of the nearly twenty singers came from the Royal Dramatic Theatre, where Moe had spent several successful years, and there was a small orchestra and a small ensemble for ballet.
This was in 1883 with Fredrich von Flotow's Martha, The Barber of Seville, Rigoletto, The Beggar Student and The Marriage of Figaro.
