Most of the posts on the Cantum Mensurable blog have focused on sacred music, in particular Latin polyphony. The corpus of Portuguese music of the sixteenth and seventeenth centuries is rich in para-liturgical and religious thematic music being the villancico in the centre of this interesting repertory. In the case of the villancicos, most authors are lesser known than the sacred polyphony and sometimes these works are the only surviving music output of the composers.
