No longer rounded, the walls were straight and flat, and covered with a white plaster or thick paint that made them smooth and even. And innumerable tiny tiles covered the walls, arranged in tiers from the smooth marble floor up to the arched ceiling. First, there was a thick band of blue and green, arranged in zig-zags, stars, squares, and pyramid shapes, going up two or three hooves. Then, there was a blank space of creamy-white wall, followed by another ornate arrangement going up just beneath the ceiling, this time with turquoise and gold forming exotic shapes that resembled fabric or knotted string. At the top, the arrangement was surmounted with miniature buttresses and arches, with depictions of the phases of the moon repeated throughout.
