Domenico Massenzio (28 March 1586 – 23 October 1657) was an Italian baroque composer.
His lifetime «coincides perfectly with the conception and implementation of the Counter-Reformation, the largest-scale operation of ideological communication ever carried out in Europe».
[1] He worked at the Seminario Romano (1612), Collegio Inglese (1624-6), Cappella Giulia (1626-7).
His first two collections of music (the 'Sacrae cantiones' in 1612 and the 'Motecta [...] liber secundus' in 1614), were dedicated respectively to Cardinal Odoardo Farnese and to Cardinal Benedetto Giustiniani (1544-1621), a Jesuit and a great appreciator of music.
In 1631 he wrote the Sacri Mottetti «to be sung by ordinary voices or again by nuns».
