Missa Brevis is a part of the multimedia production Revelations, which is based on the striking visions of the 13th-century poetess and mystic Hadewijch d’Anvers (s.d. - 1248).

Hers are among the most astonishing writings in the history of our literature. In her Visions, in the tradition of mediaeval Christian mysticism, she describes an ecstatic loving relationship with the divine Other, the key word is passion.

This work contains 5 parts: Kyrie, Gloria, Sanctus, Agnus Dei and Halleluja.
