ARCUS NOVUS (DIOCLETIANI)
* mentioned in the Regionary Catalogue in
, and ascribed to Diocletian in the Chronograph of 354 A.D.
(p. 148). This is probably the marble arch, adorned with trophies,
which spanned the via Lata, close to the north-east corner of the present
church of S. Maria in via Lata, and was destroyed by Innocent VIII
(1488-1492). The last remains disappeared in 1523 (LS i. 217
fragments of a relief found at this point in the sixteenth century, and now
in the Villa Medici, probably came from this arch. The inscription-
VOTIS X VOTIS XX
(CIL vi. 31383
)-suggests that on the arch of Constantine. If this was the arch of Diocletian, and the inscription belongs
to it, it was probably built in 303-304 (BC 1895, 46
; Jord. ii. 102
