"The only evidence of Marenzio’s date of birth is the statement made in 1588 by his father, a Brescian notary clerk, that his son Luca, a musician then in the service of the Grand Duke of Tuscany, was 35 years old. Guerrini has suggested that he was named after the saint whose feast falls on 18 October, which would give him a birthdate of 18 October 1553" (Source:Grove Music Online) — P.davydov 09:53, 28 March 2009 (EDT)
