Attila (opera) Attila is an opera in a prologue and three acts by Giuseppe Verdi to an Italian libretto by Temistocle Solera, based on the 1809 play Attila, KÃ¶nig der Hunnen (Attila, King of the Huns) by Zacharias Werner. The opera received its first performance at La Fenice in Venice on 17 March 1846.
Baroque opera (1600-1750) The first opera ever written was performed in 1597 in Florence in Italy. It was called Dafne and the composer was Jacopo Peri. This opera is now lost, but three years later, in 1600, he worked together with another composer called Giulio Caccini to write an opera called Euridice. The music for this still exists. It was nearly all recitative.
