POMERIUM—PONS AELIUS
the face where the distance to the next stone was inscribed has been
broken off.
The termination of Trajan is thought to be recorded in a coin of 107 (?)
(Cohen, Trajan 539), which was restored in two contorniates (BC 1919,
35-38).
Under Hadrian in 121 a.d. the line was again marked out, and four
of his cippi have been found, but they record a restoration and not an
extension :
(n) CIL vi. 1233 a = 3i539 a ; NS 1887, 181 ; BC 1887, 149, found
in 1867 under No. 18 Piazza Sforza Cesarini, with the number vi on
the left side and p . cccclxxx on the right (h in text fig. 4).
(0) CIL vi. 3t539 ^ found in 1732 or 1735 in the foundations of
a wall near S. Stefano del Cacco (i in text fig. 4).
(p) CIL vi. 1233 b — 31539 c, copied in the sixteenth century “ ante
domum Caesiam,” which gives no evidence of its original locality.
(q) There seems to be good reason for accepting the account of
Ligorio (Taur. xv. 205) of the discovery of a cippus near the so-called
Porta Chiusa (marked Porta (I), just south of the Castra Praetoria in
text fig. 4); the text is identical with that of CIL vi. 31539 a (LS ii. 248).
For Commodus we have Cohen, Comm. 39, 40, 181-185 (BC cit. 39-43).
For a full discussion of the pomerium during the empire, see Jord,
h I. 319-336 ; Hermes 1886, 497-562 ; 1887, 615-626 ; Mel. 1901, 97-99 ;
CIL vi. pp. 3106-3107 ; BC 1896, 246-248 ; NS 1913, 69 ; Homo, AuHlien
224-231.
A comparison of the cippi thus far found seems to justify certain
conclusions :
(1) that north of the Pincian the pomerium of the empire lay some-
what beyond the line of the Aurelian wall ; (2) that the thirteenth, and
most of the twelfth, region of Augustus lay within it ; (3) that at some
points (cf. (ά), (tf), (&) ) pomerium and wall coincided ; (4) that, whatever
may have been the case with the line of Claudius (see above), the pomerium
of Vespasian and Hadrian crossed the campus Martius approximately
from the ara Ditis to the south end of the Saepta (cf. (n), (0) ), and that
the part of the campus north of this line was outside the pomerium ;
(5) that the discovery of one stone (m) does not, under the circumstances,
make it probable that Vespasian extended the pomerium across the
Tiber ; (6) that the distances from the next cippi which are indicated
on two stones (ky n), and the inscribed numbers do not afford sufficient
data to enable us to draw the rest of the line except possibly for part
of that of Claudius.
