Keiser dominated the Hamburg opera scene between 1697, when Adonis was first performed, and 1717, resuming activities there some six years later. Christian Postel’s plot centres around Ovid’s celebrated account of the love affair between Adonis and Venus, who, in this version of the story is jealously watched over by Mars. Postel’s libretto is very long-winded and not well-sustained; but it offered Keiser the opportunity to provide over three-and-a-half hours of music, much of which, especially in Act III, is of enormous charm and variety.
