MARCIA TEPULA JULIA ENTERING ROME
MARCIA ETC. WITHIN THE WALL.
The upper view shews the exterior of the wall, with the three specus passing through it, under an arch of the Claudian arcade, now destroyed. These are carried upon one of the piers of the Marcian arcade, built of squared stone, as the part near Rome always was. In the left lower corner of this view may be seen the Anio Vetus, half underground, as usual for this aqueduct. [This opening has been built up since the photograph was taken. The demolition of all traces of the old aqueduct as far as possible was part of the plan of the architect, who directed what were miscalled the restorations of the City wall.]
The lower view represents the specus of the Aqua Marcia, of squared stone, carried on one of the arches of the Marcian arcade through the wall, within it at the same point as that of the exterior shewn above.
