Secrets of the Sistine Chapel

The Sistine Chapel is a massively important work of art, a remarkable feat, and overwhelming to experience. By the time you have walked miles to get to there, exhaustion sets in. Everyone is tempted to focus immediately on the ceiling and in doing so they miss the greater context of the chapel. So, what is the importance of the entire chapel? Here’s my take on how to understand what it all means.

The chapel is impossible to capture in photographs, and to best visualize it, the Vatican Museums provide a 360 virtual tour.

My First Tip: Don’t Look up at the Ceiling! The entirety of the chapel is best understood through the four major commissions completed by seven artists under three popes over eighty years. We will take them in chronological order.

There are three wall fresco sections surrounding the chapel: the lowest level is painted faux-drapery, the middle section are fifteenth-century narrative scenes, and the highest section is portraits of early popes. Focus initially on the middle wall frescoes from the 1480s—they are the key to understanding why this chapel is decorated the way it is. When these were completed, the vault (ceiling) was painted blue with stars to evoke a heavenly ambiance.

Find Pietro Perugino’s Christ Giving the Keys to St. Peter on the lower wall. (It is the second to last fresco on the left as you enter the chapel as a visitor; on the virtual tour it is the second fresco on the right-hand side as you enter.)

Perugino came to Rome along with other Tuscan artists to serve Pope Sixtus IV. Sixtus IV’s definitive project was the renovation and redecoration of the papal palatine chapel, now known as the Sistine Chapel, named after Sixtus. Because only the most privileged and erudite would enter into the chapel, it was paramount that the fresco cycles for the new chapel convey a message of papal authority and affirmation of the legitimacy of the pope. Scenes for the walls were specifically chosen to underscore divine rule and church law, with one side featuring Old Testament scenes from the Life of Moses and on the opposite wall New Testament scenes from the Life of Christ.

Perugino’s fresco features three horizontal planes to provide organization. It is a testament to late fifteenth-century Tuscan painting that was so admired by patrons. The scene is well-balanced with key figures in the foreground, a middle ground with smaller-sized figures and three architectural structures. A calm landscape with a blue sky and a few clouds opens up beyond the piazza.

The foreground scene is straight out of scripture, with Christ presenting a large key to a humbled and kneeling St. Peter. Perugino’s scene is orderly, peaceful, and presents a clear transfer of church leadership from Christ to Peter, and now to the pope. The conveyance of power would have been immediately apparent to fifteenth and sixteenth century visitors.

Michelangelo’s Ceiling

From Moses to Jesus and beyond, Sixtus laid the groundwork to strengthen his power and authority. Some twenty years later, Sixtus’s nephew was elected pope and took the name Julius II. He intended to expand the message of authority and hired Michelangelo to paint the ceiling in 1508. Michelangelo goes back further in time to the biblical beginning in Genesis to reinforce the direct connection between the Old Testament and the pope.

The central spine has nine scenes grouped into threes: the Noah scenes (Sacrifice of Noah, The Flood, and the Drunkenness of Noah), the creation scenes (Creation of Adam, Creation of Eve, and Fall of Adam and Eve and Expulsion), and the God scenes (Separation of Light from Darkness, Creation of the Sun, Moon, and Plants, and Separating Waters from Land). The God scenes are closest to the altar (where visitors now enter). Entering as originally intended from the Noah scenes, a visitor would proceed from sin to creation and wonder.

Michelangelo’s reading of Genesis includes depictions of the ancestors of Christ in the triangular-shaped spandrels on the sides, and the colorful and powerful prophets and sibyls along either side of the spine and the two end caps. Lunettes around the windows feature the ancestors of Christ. One cannot go back any further than the creation of the universe to link God to the authority of the pope.

Michelangelo created an innovative visual language to organize and communicate the theological message, including some 343 figures. He used a series of narrative scenes supplemented by depictions of the ancestors of Christ and other figures to connect the concept.

Instead of creating a single focus on one narrative scene read from right to left or front to back, Michelangelo’s concept requires the viewer to look and read the chapel from up, to each side, and along the walls. Michelangelo intended the faithful to take it all in from different viewpoints. The concepts of sin, salvation, creation, and history of the Church are presented as a whole through a culmination of the scenes and figures. It all ties together from the lower wall scenes closer to earth to the divine scenes of God above. If you are in the chapel, walk around and view the frescoes from different vantage points.

Michelangelo depicts many of the human forms in all their glory as God intended—naked. It was a first in the early modern era. In the Creation of the Sun, Moon, and Plants we see two Gods. One is seen from behind (a bold move on his part to represent God’s nude backside) reaching towards the newly created plants, and another of God decisively pointing to the sun while his left arm separates the moon. In the triad of last scenes, God is the superhero, painted much larger than other figures. Michelangelo does not repeat a “formula” of figural arrangements like some of his earlier peers. Each scene stands on its own.

The theological concept and figural representations were groundbreaking. The ceiling represents a stark contrast to the fifteenth-century wall paintings. Michelangelo’s figures move. The colors clash. People aren’t neatly lined up with a distinct middle point in the painting with receding space. Michelangelo does away with traditional Renaissance perspective. There is little or no landscape or background, rendering the scenes flatter, but easier to see from below.

The Missing Tapestries

Raphael’s tapestries form the third Sistine masterpiece. They were installed on the lowest level of the wall where the painted faux fabric is located seven years after Michelangelo finished the ceiling. Not wanting to be outdone by Julius II, his successor Pope Leo X commissioned Michelangelo’s rival Raphael to design ten tapestries depicting the lives and preaching of Saints Peter and Paul. The tapestries can be found in the Vatican Museums Pinacoteca, not in the Sistine Chapel.

The ten tapestries depict the Acts of the Apostles and enhance the themes of papal power and majesty. Raphael prepared full-size drawings for each massive tapestry, which were then woven in Brussels. It took almost as long to design and weave the tapestries as it did to paint the ceiling. Tapestries were luxury items costing Leo X to drain the coffers, along with paying for his other art projects.

The palette of yellows, blues, and red complimented the Florentine frescoes when hung in place. Gold and silver filament threads brought highlights and definition to the scenes, and differentiated light and dark, shadow and form. He intended the wall hangings to look more like paintings to blend in and complement the earlier frescoes and Michelangelo’s ceiling. The tapestries correspond harmoniously with the wall frescoes in size and proportion.

Raphael’s tapestry depicts St. Paul Preaching in Athens, where Paul addressed locals and professed the gospel. It became the standard representation of his evangelization in Athens. Paul envisioned a universal church, brought together in Christ’s love, open to pagans, Gentiles, and Jews. Paul defined himself as an authoritative figure who received teaching directly from Christ, although he did not know Jesus directly. He was arrested and brought to Rome, where he was martyred.

Last Judgement

Michelangelo began the final Sistine masterpiece in 1536, twenty-four years after frescoing the vault. Pope Paul III wanted to leave his own mark on the chapel altar wall and commissioned a rendering of humanity’s final judgement. To make room, existing frescoes by Perugino were destroyed, along with two of Michelangelo’s fresco sections.

Initially, the Last Judgement appears as a hodge-podge of rising and falling bodies with a luminous Christ in the center. Figures in the top band are larger than figures rising from the dead or sent to hell. Christ raises his right hand in a motion to indicate resurrection while his left hand points to his wound from crucifixion.

Reading the Last Judgement across and around the entire chapel instead of up and down helps tie in the themes. Michelangelo has constructed three horizontal bands of figures. Christ, and various saints in the uppermost band, a middle band with those rising and those descending, and the lowermost band with bodies resurrecting and those arriving and suffering in hell.

The humans rising or falling correspond to the fifteenth-century wall frescoes to the left and right of the Last Judgement. Christ and the saints, especially St. Peter, are aligned with the Sistine Chapel's fifteenth-century portraits of popes on the walls.

The key to understanding the chapel art is not to consider each painting individually, but to think of it as a harmonious concept. The Sistine Chapel contains a marvelous combination of Christ’s ancestors, prophets, prophetesses, Old Testament figures and scenes, New Testament scenes, and the final judgement of humanity, all to convey messages about the universal church and the supremacy of the pope.

My final words of advice if you intend to visit the chapel: hire a trusted guide and go during off-hours on a semi-private tour.
