I'm hoping to enlist the help of the Blogging Pompeii community to assist me in placing an image published by the Eschebach's in 1995 (left). The image is of the exit of a sewer through the southern city wall. I believe this is the same sewer discussed by Cozzi and Solgiano (1900) in the Forum and found by P. Arthur (1986) in 1980's beneath the via Marina. My best guess is that this image shows the area just to the northwest of the Porta Marina's pedestrian entrance, with the end of the Suburban baths' eastern colonade / arcade being slightly out of the frame to the left (red circles in map).
Can anyone confirm or refute this? Facts, opinions, and wild speculation alike are appreciated.
