Orlande de Lassus (also Orlandus Lassus, Orlando di Lasso, Roland de Lassus, or Roland Delattre) (1532 (possibly 1530) ? June 14, 1594) was a Franco-Flemish composer of late Renaissance music. Along with Palestrina he is today considered to be the chief representative of the mature polyphonic style of the Franco-Flemish School, and he was the most famous and influential musician in Europe at the end of the 16th century.
