Negative feature likely represents a cut through the mosaic and concrete feature in the western half of room H-10 to rob out a pipe associated with a previous water feature in the location of 7403. The cut bisects the remains of the mosaic leading to the separation of mosaics 7401 and 7402. Cut seems to be related to the spoliation of the water feature at some point after the construction of the mosaic, but before the digging of cut 7266.
