A kneeling figure in rich red vestments dominates the foreground, his hands pressed together in prayer and his head bowed in solemn devotion. The man is shown in profile, his gaze lowered, with a short fringe of brown hair and a youthful, clean-shaven face. Resting across his shoulders and extending diagonally through the composition is a large iron gridiron, its black bars sharply outlined against the lighter background.

The red robe is embroidered with intricate gold patterns along the edges, catching the light and contrasting with the plain white garment beneath. Soft, natural light falls from the upper left, illuminating the folds of the fabric and casting gentle shadows that model the figure's form. Behind him, a tranquil landscape unfolds with rounded green trees and a pale blue sky, rendered in delicate, almost misty brushwork that recedes into the distance.

The composition is tightly focused on the saint, with the gridiron forming a strong diagonal that leads from the lower left to the upper right, anchoring the viewer’s attention on the act of prayer. Fine, smooth brushstrokes describe the textures of skin, fabric, and metal, while the background trees are painted with softer, stippled touches. Gold highlights on the robe shimmer against the deep red, and the overall palette is warm and restrained, dominated by earth tones and gentle greens.

The figure’s expression is serene and concentrated, suggesting a moment of spiritual reflection or martyrdom. No other human figures are present in the composition, and the kneeling figure is alone in the scene. The lower left corner of the painting shows the dark base of the gridiron resting on the ground, partially surrounded by shadow.

The background trees on the right are densely clustered, with their rounded foliage rendered in a range of muted greens and ochres. A subtle highlight runs along the top edge of the figure’s right sleeve, accentuating the crisp fold of the white fabric.
