According to the Internet source given below, Jacobus Vaet was a Franco-Flemish composer. Kapellmeister to the Archduke Maximilian in Prague from 1554, and when Maximilian succeeded as Emperor in 1564 became court Kapellmeister in Vienna. His output consists almost entirely of church music, including many parody Masses on models by composers such as Josquin des Préz
, Mouton and Thomas Créquillon
. His earlier work is solidly imitative in the manner of Nicolas Gombert
, but his later music shows the influence of Orlando di Lassus
in its freer textures and bold dissonances, and of the Venetians in his double choir pieces.
