Nibby, Analisi, II, p. 501: "A destra della contrada degli Arconi due cippi simili a quelli del pomerio di Roma furono scoperti nel risarcire la strada Tanno 1824."
Some of the paving stones are still to be seen in situ under the modern wall which runs up from the brick reservoir of imperial date. This wall was to sustain the refuse which was thrown over the city wall. The place between the walls is now a garden.
I have examined with care every foot of the present western wall on which the houses are built, from the outside, and from the cellars inside, and find no traces of antiquity, except the few stones here and there set in late rubble in such a way that it is sure they have been simply picked up somewhere and brought there for use as extra material.
C.I.L., XIV., 3029; PED XXC. Nibby, Analisi, II, p. 497, mentions an inscription, certainly this one, but reads it PED XXX, and says it is in letters of the most ancient form. This is not true. The letters are not so very ancient. I was led by his note to examine every stone in the cyclopean wall around the whole city, but no further inscription was forthcoming.
