Orlande de Lassus (whose name is also spelt Orlandus Lassus, Orlando di Lasso, Roland de Lassus, or Roland Delattre) (born Mons, Hainaut, probably in 1532 ; died Munich, 14 June, 1594) was a Franco-Flemish composer who lived in the last part of the Renaissance. Lassus and Palestrina are the two most famous composers of that time who were writing church music in a polyphonic style.
