One of a series of mythological works executed by Botticelli after his return from Rome in 1482. The painting was commissioned by a cousin of Lorenzo Medici, Lorenzo di Pierfrancesco, who was to become a faithful patron of Botticelli's work. ... It was probably painted as a celebration of the marriage of Lorenzo di Pierfrancesco de' Medici in 1482. http://www.italian-renaissance-art.com/Primavera.html
