Who painted this picture?

The Birth of Venus is a painting by Sandro Botticelli generally thought to have been made in the mid 1480s. It has long been suggested that Botticelli was commissioned to paint the work by the Medici family of Florence, Italy, specifically by Lorenzo di Pierfrancesco de' Medici (1463-1503) under the influence of his cousin Lorenzo de' Medici, a major patron of Botticelli. However, no originating documents associated with the painting survive, and its first linkage with the Medici family is not recorded until several decades after the supposed date of its creation, namely in the 1550 edition of Vasari's Lives. It depicts the goddess Venus, having emerged from the sea as a fully-grown woman, arriving at the shore (this theme is related to the Venus Anadyomene motif). The painting is in the collection of the Uffizi Gallery in Florence.
