Maria Salviati, Italian noblewoman (d. 1543)
Maria Salviati (17 July 1499 – 29 December 1543) was an Italian noblewoman, the daughter of Lucrezia di Lorenzo de' Medici and Jacopo Salviati. She married Giovanni delle Bande Nere and was the mother of Cosimo I de Medici. Her husband died 30 November 1526, leaving her a widow at the age of 27. Salviati never remarried; after her husband's death she adopted the somber garb of a novice, which is how she is remembered today as numerous late portraits show her attired in black and white.
