David is a masterpiece of Renaissance sculpture created between 1501 and 1504, by the Italian artist Michelangelo. Standing 17 feet in height, the statue represents the Biblical hero David, a favored subject in the art of Florence. Originally commissioned as one of a series of statues of prophets to be positioned along the roofline of the east end of the Cathedral of Florence, the statue was placed instead in a public square, outside the Palazzo della Signoria, the seat of civic government in Florence, where it was unveiled on September 8, 1504. Because of the nature of the hero it represented, the statue soon came to symbolize the defense 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 political power of the Medici family. The eyes of David, with a warning glare, were turned towards Rome. The statue was moved to the Galleria dell'Accademia, Florence, in 1873, and later replaced at the original location by a replica as seen in this photo.
In Greek mythology Medusa ("guardian, protectress") was a monster, a Gorgon, generally described as having the face of a hideous human female with living venomous snakes in place of hair. Gazing directly into her eyes would turn onlookers to stone. Medusa was beheaded by the hero Perseus, who thereafter used her head as a weapon until he gave it to the goddess Athena to place on her shield.
