Ernelinde is Philidor's most important serious opera and it marked an epoch at the Paris Opéra. It is a thoroughly human drama dispensing entirely with the supernatural; it is in three acts not five; and while it retains the spectacular elements and choruses normal in French opera it is replete with lengthy arias in an Italianate style. It is moreover directly influenced by Gluck. Ernelinde was actually more successful with the public when revived in 1777 by which time Gluck's works were well established. However its bold and compellingly dramatic ideas deserve our attention for its own sake. The libretto is by A. A. H. Poinsinet after Noris.
