John Taverner (c.1490-1545), not to be confused with 20th Century composer John Tavener, was a shining example of English Renaissance composition. Arguments among scholars continue as to whether or not he was involved with Cromwell or ever in any way moved into the Protestant camp. He did at one time have certain "heretical" materials in his possession, but they may have been largely musical in nature, since some of his works seem to have a "Lutheran" influence. Taverner wrote a number of Masses, Magnificats, and other church pieces and is credited with developing the In Nomine as an ecclesiastical musical form. He also wrote secular pieces, although the exact number is unsure, since some may not have survived.
