Apse Mosaic (detail) is a striking example of Byzantine mosaic art, typically found in the apse of early Christian churches. Byzantine mosaics were known for their use of shimmering gold and vibrant colors, often depicting religious figures and scenes. This particular mosaic shows intricate details of saints, angels, or Christ, rendered in rich colors and set against a golden background.

The mosaic is made up of small, precisely arranged tesserae (glass or stone tiles), creating a luminous, otherworldly effect. Byzantine mosaics were designed to convey the divine presence, and this detail exemplifies the meticulous craftsmanship and spiritual significance of this art form.
