'''Dioclesian''' (or '''The Prophetess''', or '''The History of Dioclesian''') is a
tragicomic semi-opera in five acts by
Henry Purcell to a
libretto by
Thomas Betterton based on the play ''
The Prophetess'', by
John Fletcher and
Philip Massinger, which in turn was based very loosely on the life of the Emperor
Diocletian. It was premiered in late May of 1690 at
Queen's Theatre, Dorset Garden. The play was first produced in 1622.
[1] Choreography for the various dances was provided by
Josias Priest, who worked with Purcell on several other semi-operas.
Synopsis
The story is about the struggle for power in
Ancient Rome. Delphia, a
prophetess, foretells that Diocles, a footsoldier, will become emperor after he kills a "mighty
boar". Diocles does not take the prophesy seriously, and jokes that if this occurs he will marry Delphia's ill-favored niece Drusilla. It turns out that a soldier, Volutius Aper, nicknamed "the boar" has murdered the old emperor, and Diocles kills Aper in revenge. In reward for this action he is made co-emperor and renames himself Dioclesian. He ignores his promise to marry Drusilla, and courts the princess Aurelia instead. This angers Delphia, who brings a stop to the wedding ceremony by conjuring a storm and giant monster. She then causes the princess to fall in love with Diocles' rival Maximillian, and the
Persians to defeat the Roman army. Diocles realises the error of his ways, routes the invaders, cedes his half of the throne to Maximillian, and moves to
Lombardy with Drusilla.

Betterton added scenes in order to make space for Purcell's music. Some of these additions were not appreciated at the time because they broke off the flow of drama of the play. The most famous scene from ''Dioclesian'' is the final
masque, a self-contained
pastoral which remained popular into the eighteenth century about
Cupid taming
Jupiter.

The premier production had a Prologue written by
John Dryden that was suppressed after only one performance; it was considered too sensitive politically during King
William's military campaign in
Ireland.
