Gregorian chant as plainchant experienced a popular resurgence during the New Age music and world music movements of the 1980s and '90s. The iconic album was Chant, recorded by the Benedictine monks of Santo Domingo de Silos, which was marketed as music to inspire timeless calm and serenity. It became conventional wisdom that listening to Gregorian chant increased the production of beta waves in the brain, reinforcing the popular reputation of Gregorian chant as tranquilizing music. Gregorian chant has often been parodied for its supposed monotony, both before and after the release of Chant. Famous references include the flagellant monks in Monty Python and the Holy Grail intoning "Pie Jesu Domine." The asteroid 100019 Gregorianik is named in its honour, using the German short form of the term. Gregorian chanting has been also used in Vision of Escaflowne anime series. Gregorian chant-like music was composed for the Xbox game Halo as the main theme, written by Marty O'Donnell and Michael Salvatori. On the original Halo: Combat Evolved the theme was sung by the two composers and three other singers (from the liner notes of the Halo Original Soundtrack). In later installments the theme was performed by a sixteen piece choir (Halo 2) and a 24 piece choir (Halo 3). Also in the anime series of Death note, a theme named Kyrie has the gregorian chant style.
The Catholic Reformation was not only a political and Church policy oriented movement, but it also included major figures such as Ignatius of Loyola , Teresa of Ávila , John of the Cross , Francis de Sales , and Philip Neri , who added to the spirituality of the Catholic Church. Teresa of Avila and John of the Cross were Spanish mystics and reformers of the Carmelite Order , whose ministry focused on interior conversion to Christ, the deepening of prayer, and commitment to God's will. Teresa was given the task of developing and writing about the way to perfection in her love and unity with Christ. Her publications, especially her autobiography The Life of Theresa of Jesus , had multiple effects. Thomas Merton called John of the Cross the greatest of all mystical theologians.
