Michelangelo's Davi, sculpted from 1501 to 1504, is a masterpiece of Renaissance sculpture and one of Michelangelo's two greatest works of sculpture, along with the Pietà . It is the statue of the young Israelite king David alone that almost certainly holds the title of the most recognizable stone sculpture in the history of art. It has become regarded as a symbol both of strength and youthful human beauty. The 5.17 meter (17 ft)marble statue portrays the Biblical King David in the nude, at the moment that he decides to battle with Goliath. It came to symbolize the defense of civic liberties embodied in the Florentine Republic, an independent city state threatened on all sides by more powerful rival states and by the hegemony of the Medici themselves. This interpretation was also encouraged by the original setting of the sculpture outside the Palazzo della Signoria, the seat of civic government in Florence. The completed sculpture was unveiled on 8 September 1504.
