The Birth of Venus to Botticelli's Florentine contemporary, and Lorenzo di Medici's court poet, Angelo Poliziano. The iconography of "The Birth of Venus" is similar to a description of a relief of the event in Poliziano's poem the "Stanze per la giostra", commemorating a Medici joust in 1475, which may also have influenced Botticelli, although there are many differences. For example Poliziano talks of multiple Horae and zephyrs. Older writers, following Horne, posited that "his patron Lorenzo di Pierfrancesco asked him to paint a subject illustrating the lines", and that remains a possibility, though one difficult to maintain so confidently today.

Portrait of a Young Woman (Botticelli, Frankfurt) Portrait of a Young Woman (Botticelli, Frankfurt) Portrait of a Young Woman is a painting which is commonly believed to be by the Italian Renaissance painter Sandro Botticelli, executed between 1480 and 1485. Others attribute authorship to Jacopo da Sellaio. The woman is shown in profile but with her bust turned in three-quarter view to reveal a cameo medallion she is wearing round her neck. The medallion is a copy in reverse of "Nero's Seal", a famous antique carnelian representing Apollo and Marsyas, which belonged to Lorenzo de' Medici. It is housed in the Städel Museum of Frankfurt, Germany. Other
