Re Lear in the context of Salvadore Cammarano

Macbeth (Italian pronunciation: [ˈmakbet], also [makˈbɛt]) is an opera in four acts by Giuseppe Verdi, with an Italian libretto by Francesco Maria Piave and additions by Andrea Maffei, based on William Shakespeare's play of the same name. Written for the Teatro della Pergola in Florence, Macbeth was Verdi's tenth opera and premiered on 14 March 1847. It was the first Shakespeare play that Verdi adapted for the operatic stage. Almost twenty years later, Macbeth was revised and expanded into a French version and given in Paris on 21 April 1865.

After the success of Attila in 1846, by which time the composer had become well established, Macbeth came before the great successes of 1851 to 1853 (Rigoletto, Il trovatore and La traviata) which propelled him into universal fame. As sources, Shakespeare's plays provided Verdi with lifelong inspiration: some, such as an adaption of King Lear (as Re Lear) were never realized, but he wrote his two final operas using Othello as the basis for Otello (1887) and The Merry Wives of Windsor as the basis for Falstaff (1893).

Antonio Somma (28 August 1809, Udine – 8 August 1864, Venice) was an Italian playwright who is most well known for writing the libretto of an opera which ultimately became Giuseppe Verdi's Un ballo in maschera in 1859. While a student, his tragedy, Parisina, gave him quite a success.

Initially, his contact with Verdi came about when the composer was seeking to continue work on his proposed Re Lear, an adaptation of the Shakespeare play, King Lear, for the opera stage which had begun under his long-time collaborator Salvadore Cammarano who had died. Under Verdi's supervision, Somma wrote the libretto for Re Lear, a project that Verdi never realised musically although extensive work was done and a full libretto completed to the point where Verdi was considering this to be the opera he wrote for Naples for the 1858 season.
