Josquin des Prez (French: [ʒɔskɛ̃ depʁe]; c. 1450/1455 – 27 August 1521), often referred to simply as Josquin, was a French composer of the Renaissance. His original name is sometimes given as Josquin Lebloitte and his later name is given under a wide variety of spellings in French, Italian, and Latin, including Iosquinus Pratensis and Iodocus a Prato. His motet Illibata Dei virgo nutrix includes an acrostic of his name, where he spelled it “Josquin des Prez”. He was the most famous European composer between Guillaume Dufay and Giovanni Pierluigi da Palestrina, and is usually considered to be the central figure of the Franco-Flemish School. Josquin is widely considered by music scholars to be the first master of the high Renaissance style of polyphonic vocal music that was emerging during his lifetime.
