A layer of post-abandonment accumulation that filled the robbery cut (5409) of wall 5346, which divided rooms 3 and 4. Excavation revealed part of the construction cut for wall 5337 and its fill (not documented), suggesting that wall 5346 would originally have covered this, and thus that wall 5346 would post-date wall 5337. This layer was covered by layers previously excavated by the Sopraintendenza, and thus its stratigraphic reliability is poor.
