"The Calling of St. Matthew" depicts the moment when Jesus, accompanied by Saint Peter, calls Matthew, the tax collector, to become one of His disciples. The scene is set in a dimly lit, somewhat squalid room, which was characteristic of Caravaggio's style. The stark contrast between light and shadow plays a crucial role in the composition, drawing the viewer's attention to the main figures and the divine encounter. The focal point of the painting is the interaction between Jesus and Matthew. Jesus, on the right side of the canvas, points towards Matthew with a divine and radiant gesture, while Matthew sits at a table, surrounded by other tax collectors, in apparent shock and disbelief at the unexpected call. The facial expressions and body language of the characters convey the emotional intensity of the moment. Caravaggio's attention to detail is evident in the realistic portrayal of the characters' expressions, their clothing, and the textures of objects within the scene. The use of light illuminates Jesus and Matthew, emphasizing their significance in the composition. One of the most compelling aspects of this artwork is how Caravaggio masterfully conveys the contrast between the sacred and the mundane. The divine light that shines on Jesus and Matthew creates a stark juxtaposition with the dark, everyday setting and the worldly men gathered around the table. This contrast underscores the transformative power of the divine call.
