Who was Mona Lisa in da Vinci’s famous masterpiece?

Although it’s known as the Mona Lisa, Leonardo da Vinci’s famous
painting was originally titled La Giaconda. Painted on wood, it’s a por-
trait of Lisa Gherardini, the wife of a Florentine merchant. X-rays
reveal that Leonardo sketched three different poses before settling on
the final design. The painting of Lisa has no eyebrows because it was
the fashion of the time for women to shave them off.
