CAMPUS IOVIS
mentioned only once (Hist. Aug. Pescenn.
12), with no
indication of its location. It has been suggested that it
might have been
in
Region VII, near the
NYMPHAEUM IOVIS of Reg.,
and that this may
have been built by Diocletian, who assumed the
cognomen of Iovius as a
sign of his devotion to the cult of Jupiter (Pr. Reg. 110,
136). It is,
however, more likely that it is a mere invention on the
analogy of campus
Martius (
SHA 1916, 7.A, 13).
