Leonardo da Vinci
She was the daughter of a wealthy Florentine banker, and her portrait—the only painting by Leonardo da Vinci in the Americas—was probably commissioned about the time of her marriage at age 16. Leonardo himself was only about six years older. The portrait is among his earliest experiments with the new medium of oil paint; some wrinkling of the surface shows he was still learning to control it. Still, the careful observation of nature and subtle three–dimensionality of Ginevra's face point unmistakably to the new naturalism with which Leonardo would transform Renaissance painting. Ginevra is modeled with gradually deepening veils of smoky shadow—not by line, not by abrupt transitions of color or light.
