(Click on image for high-quality PDF version)
Occurs on arch jambs at entrances to east and west side chambers of the Sala de las Dos Hermanas. Colours of the graphic are approximately correct, but originals have alternating green and honey-brown 8-rosettes. A similar mosaic remains on the floor between the arch jambs at the entrance to the Mirador de Lindaraja. This is now much worn away, and little of the original colour is left.
