(From the Choral Journal article “Dating Josquin’s Enigmatic Motet Illibata Dei virgo nutrix” by Leslie Clutterham [scroll to p.9])
Most modern analyses of Josquin’s miniature masterpiece Illibata Dei virgo nutrix have focused on the text and music of only the first part of the motet. The secunda pars, difficult toclassifY stylistically, has been largely ignored. This article reconciles various analyses in the context of the entire motet and offers some new theories regarding the date and circumstancesof its composition, as well as biographical information about its composer.
Illibata Dei virgo nutrix is included in the complete works of Josquin begun by Albert Smijers in the early part of this century. Smijers and other early analysts dated Illibata amongJosquin’s earliest works, a group largely composed of motets composed before 1500.1 It is a five-voice Marian motet with a tenor cantus firmus. It sets two rhymed verses, which Josquinalso authored.2 Howard M. Brown notes that Josquin’s nonliturgical, non-Biblical verse may indicate that it was “intended for performance in ritual or votive services in royal chapels or collegiate churches.”
