At the end of week three, the destruction of the earthquake that destroyed our building is even more apparent. The middle section of our window wall seems to be blown apart.
However, at the bottom of the fill a column appears in the plaster floor. It is the first hint indicating how the area was roofed (and explains a number of broken pieces in the fill that may have come from simple arch).
You can see the column appearing next to the upright of the frame for our shade. By the way, we also found an olive pit near the column. We will sift for more when we go back to work on Sunday.
