David is a 5.17-metre (17.0 ft)[a] marble statue of a standing male nude. The statue represents the Biblical hero David, a favoured subject in the art of Florence.
David was originally commissioned as one of a series of statues of prophets to be positioned along the roofline of the east end of Florence Cathedral, but was instead placed in a public square, outside the Palazzo Vecchio, the seat of civic government in Florence, in the Piazza della Signoria where it was unveiled on 8 September 1504. The statue was moved to the Galleria dell'Accademia, Florence, in 1873, and later replaced at the original location by a replica.
Because of the nature of the hero it represented, the statue soon came to symbolize the defence of civil liberties embodied in the Republic of Florence, an independent city-state threatened on all sides by more powerful rival states and by the hegemony of the Medici family. The eyes of David, with a warning glare, were turned towards Rome.
