I. On the level part of the vault are nine scenes from Genesis; the Eternal dividing light from darkness, the Eternal creating the sun and moon, the Eternal dividing the waters, the Creation of man, the Creation of woman, the Temptation, Cain and Abel, the Deluge, and the Drunkenness of Noah.
II. In every angle of the imaginary frame surrounding these nine scenes is a naked figure seated on a pedestal, twenty in all. Vasari calls these the "Ignudi." Between them, and below each one of the five scenes from Genesis, is a small medallion the colour of bronze.
III. At the springing of the arches of the vault, in the twelve pendentives, twelve prophets and sibyls are seated between pilasters crowned by naked children who act as caryatids and are each accompanied by two little geniuses. The figures are Jeremiah, Ezekiel, Joel, Zachariah, Isaiah, Daniel, Jonah, the Persian, Erythræan, Cumæan, Delphian, and Libyan Sibyls.
IV. Between the prophets and sibyls, in the space above the twelve arched windows, are the precursors and ancestors of Christ, groups of two or three persons divided into two sections by an archivolt in the midst of which are written on tablets the names of the precursors. Above these triangles, on the ribs, are naked youths. Between the triangles and under the thrones of the prophets and sibyls, whose names they carry on tablets, are children's figures.
V. In the four pendentives formed by the angles of the ceiling are David, Conqueror of Goliath; Judith and Holofernes; the Brazen Serpent, and the Hanging of Haman.

[29] Michelangelo abandoned painting for almost twenty years and did not take it up again until 1529.
