the libretto for purcells opera dido and aeneas is based on
Dido and Aeneas Originally based on Nahum Tate's play Brutus of Alba, or The Enchanted Lovers (1678), the opera is likely, at least to some extent, to be allegorical. The prologue refers to the joy of a marriage between two monarchs, which could refer to the marriage between William and Mary. In a poem of about 1686, Tate alluded to James II as Aeneas, who is misled by the evil machinations of the Sorceress and her witches (representing Roman Catholicism, a common metaphor at the time) into abandoning Dido, who symbolises the British people. The same symbolism may apply to the opera.[6] This explains the addition of the characters of the Sorceress and the witches, which do not appear in the original Aeneid. It would be noble, or at least acceptable, for Aeneas to follow the decree of the Gods, but not so acceptable for him to be tricked by ill-meaning spirits.
