Dioclesian, or, The History of Dioclesian is a semi-opera in five acts by Henry Purcell. Its libretto was written by Thomas Betterton based on the play The Prophetess, by John Fletcher and Philip Massinger. It was first performed in late May 1690 at the Queen\'s Theatre, Dorset Garden.

Known as one of the most beautiful and mysterious recorder songs Purcell had ever written, this Chaconne appears in act 3, after soft music and the Dance of Furies. Even though the song is in C minor, Purcell wrote it as if it were in G minor, which makes it look much easier for music lovers to read notes and play them.

This piece of music was originally written for Flutes and Bass Continuo; however, the arranger adapted it for 2 Alto Recorders (or, Flutes) & Classical Guitar.
