Alhambra, Salon de Comares

The graphic reduces the colours to two. The original colours in East and West walls of Salon de Comares are white, black, blue and green in concentric rectangles, with honey-brown round the borders. The same pattern occurs, as wooden ceilings, in the east and west alcoves of the Sala de los Abencerrajes. It also occurs as window grilles in the Hall of the Ambassadors, the Alcazar, Seville. A similar pattern, with slightly different proportions occurs on the bronze doors on the south side of the Patio del Mexuar.

• The symmetry group of the tiling is 4*2 (p4g).
• All the internal angles of the constituent polygons are a multiple of 45°.
• There is one non-regular reflective tile and one reflective pair.
• The tiling satisfies the interlace condition and has no finite interlace and one infinite interlace with straight cross-overs.
• The tiling is edge-to-edge.
• As drawn, contains about 51 polygons.
