The opera is based on a libretto adapted by the poet Silvio Stampiglia for Giovanni Bononcini, whose setting was staged at Rome’s Teatro di Torre Nona in 1694. Handel completed his opera in 1738 in little more than a month. However, his typically swift pace and resourceful treatment of musical themes and models should not be misconstrued as complacency, carelessness, or low imaginative powers. The autograph manuscript reveals that Handel invested considerable skill in arias that are perfectly tailored to the dramatic storyline, many of which were meticulously crafted and then redrafted.
'Serse' comes late in the Handel opera list, with only two more attempts at the form remaining. Adapted from the libretto originally prepared for Cavalli's 'Xerses' in 1655 (itself a great opera), 'Serse' remains true to its Venetian roots. The action, which is largely comic, moves fluidly through short arias, ariosos and ariettas. Serse is a parody of the self-important ruler; "Ombra mai fu,' possibly Handel's most famous setting of Italian words, is in fact a love song to a plane tree originally intended to be sung by a man who had been castrated. Irony does not go much deeper than this. The characters that surround Serse are an uncommonly varied lot with the plain-speaking Atalanta a particular joy.
