the alignment of these blocks, perpendicular to 7322 and 7378, and parallel to the northern wall of room 15, suggest a previous division of the space which now constitutes room 15. the relationship between 7381 and 7382 (and by extension 7397) is difficult to ascertain. while 7381 appears to cover and post-date 7382, this relationship is difficult to confirm. it is also difficult to determine the relationship with the cut 7380 and subsequent slab floor 7320.
