New Sacristy of Florence, during 1524, after Clement VII's election to the papal throne. The sculpture's termination date remains unknown; however, the works were interrupted during the Siege of Florence and resumed in 1531. The work remained visibly unfinished in 1534, the year that Michelangelo definitively left Florence. Dusk, or Sunset, is personified as man and is stretched out and nude, as are the other statues in the series. It was modelled, perhaps, after the mountain and river gods at the Arch of Septimius Severus in Rome. If its pair, Dawn is in the act of awaking, Dusk is falling asleep. The statue lies down with one leg crossing the other, for greater compositional dynamism, one arm resting on his thigh to hold back a falling cloth. The other arm is bent to support the figure. The statue's face is bearded, with a thoughtful, downward gaze. Among the various iconographic meanings proposed, the statue is seen as an emblem of the phlegmatic temperament or of the elements of water or earth. Michelangelo's study for Dusk is known for exemplifying his style of striking, unfinished drawings. Gallery of Dusk images The lantern The lantern at the top of the New Sacristy is made out of marble and has an "...unusual polyhedron mounted on the peak of the conical roof". The orb that is on top of the lantern has seventy-two facets and is approximately two feet in diameter. The orb and cross, that is on top of the orb, are traditional symbols of the Roman and Christian power, and recalls the similar orbs on central dome plan churches such as St. Maria del Fiore and St. Peter's. But because it is on a private mausoleum, the Medici family is promoting their own personal power with the orb and cross, laurel wreath, and lion heads, which are all symbols of status and power. The lantern that holds up the orb helps to accentuate the height and size of the chapel, which is fairly small. The lantern is a bit less than seven meters tall and "...is equal to the height of the dome it surmounts". The lantern metaphorically expresses the themes of death and resurrection. The lantern is where the soul could escape and go from "...death to the afterlife". The Cappella dei Principi The octagonal Cappella dei Principi surmounted by a tall dome, 59 m. high, is the distinguishing feature of
