Brief Georg Friedrich Treitschkes und Joseph Weigls an eine Intendanz, Wien, 14. Mai 1818

The "Nachtigall und Rabe" ("Nightingale and Raven", with a text by Friedrich Treitschke and music by Joseph Weigl) was first performed in the Wiener Theater am Kärntnertor on 20 April 1818. The two authors Treitschke and Weigl now offer it to another house to be performed.
