Orlande de Lassus (also Orlandus Lassus, Orlando di Lasso,Roland de Lassus, or Roland de Lattre) was a Netherlandish composer of the late Renaissance. He is today considered to be the chief representative of the mature polyphonic style of the Franco-Flemish school, and one of the three most famous and influential musicians in Europe at the end of the 16th century (the other two being Palestrina and Victoria). One of the most prolific, versatile, and universal composers of the late Renaissance, Lassus wrote over 2,000 works in all Latin, French, Italian and German vocal genres known in his time. These include 530 motets, 175 Italian madrigals andvillanellas, 150 French chansons, and 90 German lieder. No strictly instrumental music by Lassus is known to survive, or ever to have existed: an interesting omission for a composer otherwise so prolific, during an age when instrumental music was becoming an ever-more prominent means of expression. The German music publisher Adam Berg dedicated 5 volumes of his Patrocinium musicum (1573–1580) to Lassus' music.
