Geometric Mosaic with Quatrefoils

This Roman mosaic (2nd–3rd cc. AD) from Ostia features a grid of interlocking quatrefoils—four-lobed shapes—crafted from black, white, red, and gray tesserae. Likely adorning a domus or public space, it creates a visual illusion of depth and movement, reflecting Roman fascination with pattern and mathematical harmony. Such designs highlight the Roman pursuit of architectural refinement, using geometry to enhance aesthetic appeal and spatial perception.
