I quatro rusteghi

I quatro rusteghi (The Four Curmudgeons, The Four Ruffians, in Edward J. Dent's translation School for Fathers, also translated by James Benner as Foolish Fathers) is a comic opera in three acts, music by Ermanno Wolf-Ferrari to a libretto by Luigi Sugana and Giuseppe Pizzolato based on Carlo Goldoni's 18th-century play I rusteghi. The opera is written in Venetian dialect, hence "quatro" instead of "quattro".
