caption: The image shows a mosaic of St. Catherine of Siena in the Church of the Holy Sepulchre in Jerusalem, depicting her with a halo of light around her head. She is wearing a white robe with a blue sash and a golden crown, and her hands are clasped in prayer. Her eyes are closed and her expression is peaceful and serene. The background of the mosaic is a deep blue, with a golden border around the edges.
