These tiles appear to be related to the other flat-lying sections of marble and tiles (6155, 6158) in room G014 and are currently interpreted as a rudimentary floor surface used after the spoliation of the mosaics in this space. The tiles in the center of this feature have some evidence of burning, so it is also possible that this section was used as a cooking surface.
