Mette Trolle (1637 – floruit 1679), was a Danish noblewoman, poet and Catholic convert, known for her unconventional life style.
The marriage was notoriously unhappy, and Trolle mocked Reetz in public.
Mette Trolle was described as talented, educated, gifted and charming, and wrote poems in French and Dutch.
In 1670, when Griffenfeld wished to terminate their relationship and marry another, he convinced the King to appoint Jørgen Reedtz Danish ambassador to Spain and order her to accompany him there.
Regent Mariana awarded Mette Trolle a Spanish royal pension and the title Duchess of Avela.
