The Mona Lisa, a world-famous oil painting by Leonardo da Vinci from the height of the Italian Renaissance in the early 16th century, is surely familiar to you. The painting is also known as "La Gioconda" in Italian and "La Joconde" in French. It is believed to have been named after Lisa del Giocondo, a woman from Florence. The commonly used title "Mona Lisa" is based on a spelling mistake. In fact, "Mona" is derived from the Italian abbreviation "Monna," meaning "woman," and therefore is not a first name. It was the title used to address Lisa as the wife (madonna) of Francesco del Giocondo.
