This SU is a mosaic floor set in rooms I-10 and I-18. The mosaic continues uninterrupted through the threshold area between the two rooms, suggesting that they were laid at the same time. The fact that there are two separate mosaic patterns (a different pattern in each room) suggests that the mosaic was laid after walls 8199 and 8200 were already in place.
