The figure of Christ is in the top left corner of the fresco. He is making a dramatic entrance into the scene, surrounded by a halo of light and a security detail of heavenly hosts. Some of these angels look on in awe and shock at the event occurring, while others act as a protective barrier between those things which are heavenly and divine and those which are earthly and below. From Christ, a beam of light radiates down to a group of figures. This group is highly dramatized in their posing and expression. The most dramatic of these earthly figures is Saul himself. Saul has the face of an old man although “we know and Michelangelo also knew it well that the calling of Saul on the road to Damascus occurred when he was about 30 years old." Saul's face reflects Michelangelo's own, who at this point was an old man also troubled by his faith. The figure of Saul represents “the human being in need of a greater light”. Surrounding Saul is a triangular composition of companions that attempt to aid him as he lies recumbent on the ground. With one hand raised to shield himself from Christ, he has an expression of strange discomfort and fear. Most of the elements of this painting point towards the figure of Saul as being the main focus of the composition. The downward sloping hills, the beam of radiant light, and the groupings of the figures surrounding Saul make it clear to the viewer that he is the most important person in this figure-heavy piece. Further in the background is an outline of a city to contextualize the exact moment in which Saul is experiencing this divine intervention. On a journey to this city of Damascus in which he originally intended to arrest Christ followers, Saul was converted to Christianity. While Saul lies helpless on the ground, some of his companions begin to pull out weapons and shields as though they are evading an enemies attack. There is a tension to this scene that is only heightened by the individual expressions on each of the figures faces. The people on earth range from fearful to concerned. Even the angels above seem to be shaken by the actions of Christ. As he does in most of his pieces, Michelangelo pays careful attention to anatomy and gives great detail to the musculature and form of all of the figures whether clothed or nude. Even the horse is shown to have some muscularity as he recedes into the background, carrying a stray figure with him. Michelangelo's sources for anatomical knowledge were live models, dissections, and sculptures from antiquity. Anatomy played a very important role in his work and can be seen playing out in the Conversion of Saul. In his later works such as the Last Judgement and also in his Conversion of Saul, the muscularity of his figures have more of a strain to them than previous pieces. The muscles and anatomy seem contorted and elongated in ways that should not be natural and the figures are in impractical poses. Yet, this approach to anatomy works to enhance the drama of the piece. These poses and movements create a tension to the scene and highlight the miraculous nature of the event occurring.
Restoration
The work began restoration in 2002 and was finished in 2009. Methods included using a chemical solvent, ultrasonic curettes, and laser equipment. Restoration efforts revealed that Michelangelo not only painted in fresco, but he also painted in mezzo fresco and a secco. Mezzo fresco is a technique in which the artist paints the final, thin layer of plaster underneath the actual painting so that paint pigments only slightly penetrate the plaster. A secco is a technique in which the artist painted on dry plaster and was able to work more quickly and correct mistakes as opposed to other methods.
