The Lenten season of 1679 was a cold, rainy, and dreary affair. The new Pope, Innocent XI, was no supporter of the increasingly permissive nature of Roman aristocracy, and he took measures to enforce edicts prohibiting staged performances before a paying public, as well as a general ban on the appearance of women on the stage. Reluctantly granted, however, was permission for private performances, and this concession led to the fortuitous circumstances that made the premiere of Scarlatti’s first opera possible—the ingenuity of the Bernini brothers who produced the work; a liberal interpretation of “private performance”; the support and attendance of Queen Christina of Sweden; and, certainly not least, the fact that Pope Innocent had left the city during the carnival, leaving the enforcement of his conservatism to some of the very cardinals who most enjoyed and supported public theatre!
Following the triumphant success of Rinaldo, Handel’s third London opera, Teseo (1713), was intended to make the still unusual genre of opera more attractive to the English public. That in fact Handel was able to latch on to the success of Rinaldo was due, likewise, to the many stage effects and a richness of musical ideas. At the same time Teseo is in many respects an exception, since the Italian libretto of Nicola Haym is based on a French model, and therefore retains the structure of five acts which was usual in France. And Handel proved that apparently he too had grappled with the Franch opera tradition. As an exception, one finds forms here which do not fit into the standard patterns of secco recitative and da capo aria.
Teseo (HWV 9) is an opera seria with music by George Frideric Handel, the only Handel opera that is in five acts. The Italian-language libretto was by Nicola Francesco Haym, after Philippe Quinault's Thésée. It was Handel's third London opera, intended to follow the success of Rinaldo after the unpopular Il pastor fido. First performed on 10 January 1713,Teseo featured "magical" effects such as flying dragons, transformation scenes and apparitions and had a cast of notable Italian opera singers. It was a success with London audiences, receiving thirteen performances even though the stage machinery for the "magical" effects broke down, and would have received more performances had not one of the theatre's managers run away with the box office receipts.
