secco recitatives. Variants from the libretto are also noted. Act 1 Act 2 Act 3 Recordings Editions Handel's autograph score survives, with the Sinfonia and first recitatives missing, but it shows significant differences from the libretto, due to changes made for the first performances. Handel's performing score is lost. Three early manuscript copies, probably dating from 1710, are held in Vienna; one of these may have been a gift from Grimani to the future Emperor Charles VI. These copies, presumably based on the lost performing score, show further changes from the autograph. A manuscript from the 1740s known as the "Flower score" is described by Dean as "a miscellany in haphazard order". In about 1795 the British composer Samuel Arnold produced an edition based on early copies; this edition, while it contains errors and inaccuracies, has been called "probably a reasonable reflection of early performances". The Chrysander edition of 1874 has a tendency to "sweep Arnold aside when he is right and follow him when he is wrong". Musicologist Anthony Hicks calls it "an unfortunate attempt to reconcile the autograph text with Arnold and the wordbook, the result being a composite version of no authority". In 1950 Barenreiter published Hellmuth Christian Wolff's edition, prepared for the 1943 Halle revival and reflecting the casting of basses for Otto and Narcissus, even when they sing what would otherwise be the alto part in the last chorus. It presents a German adaptation of the recitatives and written out embellishments for the da capo arias as well as numerous cuts. The B-flat fugue G 37 appears as an act 2 overture along with other instrumental music. An edition by John E Sawyer appeared in 2013 as series II vol. 3 of the Hallische Händelausgabe. It is based on the 1709 version, with ballet music borrowed from Rodrigo, and contains two appendices with added and reconstructed music as well as deleted versions from the autograph.
