Luca Marenzio (also Marentio) (October 18? 1553? – August 22, 1599) was an Italian composer of the late Renaissance. He was one of the most renowned composers of madrigals, and wrote perhaps the finest examples of the form in its late stage of development, prior to its early Baroque transformation by Monteverdi.
Marenzio was born at Coccaglio, near Brescia, and died in Rome. A birthdate of October 18, 1553 has been proposed because of a statement by his father giving his age in years, and that he may have been named after the saint with his feast day on October 18.
