caption: The image shows a poster of St. Silvestre, a man with a beard and a green robe. His face is clearly visible, with a serious expression and a strong jawline. His eyes are looking directly at the viewer, and his hair is neatly combed. He is wearing a long, dark robe with a high collar and a belt around his waist. His hands are clasped in front of him, and he has a halo of light around his head.
