Neprigozhaya (Russian Непригожая, English The Ugly Girl), also known by its German language title Die Tochter des Bojaren (The Boyar's Daughter), is a one-act opera of 1873 by Ella Adayevskaya (the pseudonym adopted by the composer Elizaveta von Schultz).
The manuscript piano score bears the title, in German, Salomonida, die Tochter des Bojaren.
In the opera, Salomonida, the daughter of a boyar, is a victim of the prejudices of her father, who believes that his beautiful wife had once been unfaithful to him and has refused to even the evidence which would disprove this slander.
He persuades his daughter that she is ugly, and even fills the castle with distorting mirrors to reinforce this idea in the mind of Salomonida.
A soprano aria from the opera was performed in the mid 1870s in St.Petersburg by an unrecorded soloist with an orchestra conducted by Nikolai Rimsky-Korsakov.
