This apse-based mosaic consists of a simple, harmonious composition of large and small octagons delineated by a two-strand guilloche pattern. The small tesserae and the palette of colours – as many as ten different shades – combine to form a remarkably high-quality ensemble.
There is an astonishing variety of patterns, including realistic and stylised plant motifs, geometric patterns and three-dimensional shapes. The repertoire and handling of these elements are very reminiscent of mosaics from Aquitaine. Some are strikingly similar to those found in mosaics in the villa at Séviac.
