In this artwork, how is the Composition discussed?
In the Separation of Light from Darkness, the image of God is framed by four ignudi and by two shields or medallions. The ignudi are young, nude males that Michelangelo painted as supporting figures at each corner of the five smaller narrative scenes along the center of the ceiling. There are a total of 20 ignudi. These figures are all different and appear less constrained within their space than the Ancestors of Christ or the Bronze Nudes. In the earliest frescoes painted by Michelangelo toward the entrance of the Sistine chapel, the ignudi are paired, and their poses are similar but with minor variations. The variations in the poses increase with each set until the poses of the final set of four ignudi in the Separation of Light from Darkness bear no relation to each other.
Although the meaning of these figures has never been completely clear, the Sistine scholar Heinrich Pfeiffer has proposed that the four ignudi associated with the Separation of Light from Darkness represent day and night, which echo the theme of light and darkness. For instance, he points out that the ignudo next to God's right hand (on the side of darkness) is stretching as if awakening from sleep in the morning, that the diagonally opposed ignudo below God's knee (on the side of light) is carrying a heavy bundle of oak garlands on his shoulders, representing a daytime activity, and that the ignudo next to God's left arm is falling asleep and signifies nighttime.
Pfeiffer and other scholars have also suggested that in Michelangelo's Sistine iconography the ignudi represent angels and that the Bronze Nudes below the ignudi are fallen angels.Two shields or medallions accompany each set of four ignudi in the five smaller Genesis panels along the center of the Sistine ceiling. They are often described as painted to resemble bronze. Each is decorated with a picture from either the Old Testament or the Book of Maccabees from the Apocrypha. The subjects of the shields are often violent. In the Separation of Light from Darkness the shield above God shows Abraham sacrificing his son Isaac (Genesis 22:9–12), and the one below God shows the prophet Elijah as he is carried up to heaven in a chariot of fire (2 Kings 2:11).At the center of the composition, God is shown in contrapposto rising into the sky, with arms outstretched separating the light from the darkness. Michelangelo employed in this fresco the challenging ceiling fresco technique of sotto in su ("from below, upward"), which makes a figure appear as if it is rising above the viewer by using foreshortening. The contrapposto pose was also used by Michelangelo in his David (1501-1504). It is reported that Michelangelo painted this fresco in a single giornata, that is, a single working day of approximately eight hours. During Michelangelo's lifetime, this fresco was considered evidence of the painter's technical prowess at its peak. For instance, Giorgio Vasari (1511–1574), Michelangelo's student and biographer, wrote in 1550:"Furthermore, to demonstrate the perfection of his art and the greatness of God, Michelangelo depicted God dividing the light from darkness in these scenes, where He is seen in all His majesty as He sustains himself alone with open arms with the demonstration of love and creative energy.According to Vasari, Michaelangelo has “lifted the veil” of darkness typically found in artwork of the Renaissance, employing the skill of chiaroscuro, by combining the intense lights and extreme darks in this symbolic artwork.Art historians have noted several unusual features of this fresco. Andrew Graham-Dixon has pointed out that God has exaggerated pectoral muscles suggestive of female breasts, which he interprets as Michelangelo's attempt to illustrate "male strength but also the fecundity of the female principle." In addition it has been noted that the anatomy of God's neck is too complex and does not resemble the normal contour of the neck. The lighting scheme of the image has been noted to be inconsistent; whereas the entire scene is illuminated from the bottom left, God's neck appears to have a different light source from the right.
