Lupus Hellinck was a Franco-Flemish composer of the Renaissance, active in the first half of the 16th century. He was known for his sacred music, particularly his masses and motets. The "Missa Surge Propera" is a polyphonic mass setting, likely based on a pre-existing chant or motet theme ("Surge Propera" meaning "Arise, make haste"). The movement "Et in terra pax hominibus" is part of the Gloria section of the Mass Ordinary. Hellinck's style is characterized by smooth, imitative counterpoint and careful attention to text setting, representative of the mature Franco-Flemish polyphonic tradition that greatly influenced European music.
