A richly dressed man in armor kneels at the center of a grand staircase, his head turned upward toward two bishops who stand above him, one extending a hand in blessing. The kneeling figure is flanked by attendants, including a young page holding his red cloak and a group of onlookers who crowd the steps behind him, their faces animated with curiosity and reverence. To the left, two women in sumptuous garments stand apart, one gazing intently at the central scene while the other looks away, her elaborate headdress catching the light.

Below, a bearded man distributes coins from a tray to a throng of beggars and mothers with children, their outstretched arms and eager faces filling the lower part of the composition. The architecture rises in pale stone arches and columns, framing the upper figures and opening to a luminous sky, while the entire scene is bathed in a warm, golden light that highlights the textures of fur, metal, and fabric. Rubens arranges the figures in a sweeping diagonal, guiding the viewer's gaze from the tumult of the poor at the bottom to the solemn ritual above, with vigorous brushwork visible in the folds of drapery and the play of light across flesh and armor.

The composition is crowded yet controlled, each gesture and expression contributing to the drama of conversion and charity. The inclusion of stairs as a prominent architectural element both elevates the sacred action and allows Rubens to orchestrate a complex gathering of figures, each rendered with attention to individual character and emotion.
