Otto mesi in due ore ossia Gli esiliati in Siberia (Eight Months in Two Hours or The Exiles in Siberia) is an opera in three acts by Gaetano Donizetti to a libretto by Domenico Gilardoni.
The original story comes from the 1806 novel, Elisabeth, ou Les exilés de Sibérie (Elisabeth, or the Exiles of Siberia), written by Sophie Ristaud Cottin. Luigi Marchionni's subsequent play, La figlia dell’esiliato, ossia Otto mesi in due ore (The Daughter of the Exile, or Eight Months in Two Hours), first performed in Italy in 1820, was the more immediate basis for Gilardoni's libretto.
The opera has two later, substantially re-worked versions, Élisabeth ou la fille de l'exilé (Elisabeth, or the daughter of the exile), and Elisabetta, both of which received their first performances some 150 years after Donizetti's death.
19th century
The opera underwent many revisions and changes of title over the years, with a performance history nearly as convoluted as its plot. Its first version premiered with the title Otto mesi in due ore at the Teatro Nuovo in Naples on 13 May 1827, and was performed 50 times in its first season. In 1831, it was presented in Florence by Luigi Astolfi to only limited success as Gli esiliati in Siberia. In 1832, Donizetti revised the opera somewhat, adapting the original soprano role of Elisabetta for the popular Austro-Hungarian contralto, Caroline Ungher. He revised the opera further for its premiere in Livorno in 1833.
Between 1838 and 1840 Donizetti substantially re-worked the opera again, adding new music, for a longer version, Élisabeth ou la fille de l'exilé which was intended for performance in Paris. The new French libretto was written by Adolphe de Leuven and Léon-Lévy Runswick. The American musicologist Will Crutchfield has suggested that by this point, it had now a become virtually a separate opera from Otto mesi in due ore, although clearly retaining many elements of the original. However, the new work was never staged in Donizetti's lifetime. Donizetti subsequently offered the Italian version, Elisabetta, to Her Majesty's Theatre in London. Likewise, this version was never performed in his lifetime.
