Gioas re di Giuda

Gioas re di Giuda (Joas, king of Judah) is an Italian-language oratorio libretto by Pietro Metastasio written in 1735 for imperial court composer Georg Reutter the younger and later set by at least 25 composers. The plot is based on the life of King Joash of Judah.

The 1823 setting of an anonymous libretto by Simone Mayr, Innalzamento al trono del giovane re Gioas, is only thematically based on Metastasio's original.
