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. Another poem by
Sandro Botticelli Botticelli himself, standing at the front on the right. The painting was celebrated for the variety of the angles from which the faces are painted, and of their expressions. A large fresco for the customs house of Florence, that is now lost, depicted the execution by hanging of the leaders of the Pazzi conspiracy of 1478 against the Medici. It was a Florentine custom to humiliate traitors in this way. This was Botticelli's first major fresco commission (apart from the abortive Pisa excursion), and may have led to his summons to Rome.
