Lo Schiavo

Lo schiavo (O escravo, The Slave) is an opera seria in four acts by the Brazilian composer Carlos Gomes. The Italian libretto was by Rodolfo Paravicini, after a play by Alfredo Taunay. The opera deals with the subject of slavery, a major concern in Brazil at the time (the institution had only been abolished by the Lei àurea in 1888).
As Béhague explains, "Lo sciavo is considered in Brazil to be the best of Gomes's operas, as it reflects a national subject which required and was given new treatment."
