How tall is Michelangelo's David?
Hercules and Cacus
The "colossus" (height: 5.05 m) was originally given to Michelangelo and meant to complement the "David" but later appropriated by the Medici family as a symbol of their renewed power after their return from exile in 1512, and again in 1530. Although descriptions of its unveiling in 1534 provided verbal and written criticisms of the marble, most were instead aimed at the Medici family for dissolving the Republic and were not aesthetic.
A few of the writers of these hypercritical verses were imprisoned by Alessandro de'Medici, further suggesting a political commentary. The two harshest critics were Giorgio Vasari and Benvenuto Cellini, both of whom were champions of Michelangelo and rivals of Bandinelli for Medici patronage. Vasari lamented the change of hands from Michelangelo to Bandinelli, and the change of design. Cellini referred to the emphatic musculature as "a sack full of melons", forgetting that Michelangelo had received similar deprecation previously by Leonardo da Vinci. Neither Vasari nor Cellini can be viewed as unbiased resources due to their rivalries. The patrons (Medici family) were quite satisfied and rewarded Bandinelli greatly for his efforts with land, money, and he was later placed in charge of all sculptural and architectural programs for the Medici under Cosimo I.
David (Donatello)
Donatello's bronze statue of David (circa 1440s) is famous as the first unsupported standing work of bronze cast during the Renaissance, and the first freestanding nude male sculpture made since antiquity. It depicts David with an enigmatic smile, posed with his foot on Goliath's severed head just after defeating the giant. The youth is completely naked, apart from a laurel-topped hat and boots, and bears the sword of Goliath.
The creation of the work is entirely undocumented, and it has been given a range of datings. According to one theory, it was commissioned by the Medici family in the 1430s to be placed in the centre of the courtyard of the old Medici Palace. Alternatively it may have been for that position in the new Palazzo Medici Riccardi, where it certainly was placed later, which would place the commission in the mid-1440s or even later. The statue is recorded there by Vasari and other sources. The Medici family were exiled from Florence in 1494, and the statue was moved to the courtyard of the Palazzo della Signoria (the marble "David" was already in the palazzo). It was moved to the Palazzo Pitti in the 17th century, to the Uffizi in 1777, and then finally, in 1865, to the Museo Nazionale del Bargello, where it remains today.
