aesar (Cass. Dio xliii. 50), Augustus (Tac. Ann. xii. 23;
Cass. Dio v. 6), Nero, Trajan and Aurelian (Hist. Aug. Aurel. 21).
A recent attempt has been made (BC 1919, 24-32) by Laffranchi to
show that Augustus' extension of the pomerium occurred thrice, in
27, 18 and 8 B.C., from an examination of his coins. Those used as
evidence are Cohen, Aug. 114, 116, 117 (not 177); Babelon, Iulia 153,
155, 156; BM. Imp. i. p. 102, Nos. 628-630; 104, Nos. 637-642; cf.
An extension by Claudius in 49 A.D. is proved by unimpeachable
literary testimony (Tac. Ann. xii. 24; Gell. xiii. 14. 7) and by the discovery
of inscribed terminal cippi. These rectangular cippi bear on the top
the word Pomerium, on the front the inscription recording the fact of
the extension, and on the left side the number of the stone. This number
is found on four of the eight cippi so far discovered; on the others it has
been obliterated or was never cut.
The numbered cippi are:
