IX.4.2 Pompeii. May 2005. Looking east towards entrance on Via Stabiana.
According to Maiuri, three of the shops on the corner of this insula, appear to have had an elevated threshold of at least 0.80m above the floor of the sidewalk and what should have been the original threshold.
They clearly distinguish the brickwork/masonry of the above elevation from the original floor of the threshold.
In the third taberna (from the corner of the quadrivium) IX.4.3, only one block of the threshold appears located in its place.
