Giovanni Pierluigi da Palestrina (1526-) was an Italian composer of the Renaissance. He was the most famous sixteenth-century representative of the Roman School of musical composition. Palestrina had a vast influence on the development of Roman Catholic church music, and his work can be seen as a summation of Renaissance polyphony.
Jesu, rex admirabilis et triumphator nobilis, dulcedo ineffabilis, totus desiderabilis,
mane nobiscum, Domine, et nos illustra lumine, pulsa mentis caligine, mundum reple ducedine.
Translation (by Philip Ford):
Jesus, wondrous king and noble conqueror, ineffable delight, wholly to be desired,
remain with us, Lord, dispel the darkness of our minds and enlighten us with your light, fill the world with your sweetness.
