The existence of such a temple depends upon the evidence
of coins of Alexander Severus (Cohen, Nos. 101-104, esp. 102; cf.
,a which represent what seems to be the facade of a temple
between projecting porticus, dedicated IOVI ULTORI
. This Bigot places
(BC 1911, 80-85
) at the east angle of the Palatine, in the vigna Barberini,
fronting on the clivus Palatinus, the modern Via di S. Bonaventura.
He believes that here Elagabalus built his temple of ELAGABALUS
on a terrace erected by Hadrian, which Alexander Severus transformed
into a shrine of Juppiter Ultor, and that it was called Pentapylon, because
of its appearance; the name occurs in Not. (Reg. X). This hypothesis
cannot be said to be convincing (Geogr. Jahrb. xxxiv. 206
; DAP 2.
xi. 117; cf. Mem. Linc. 5. xvii. 530), and the difficulty is, that the
remains of brick-faced concrete at the edge of the hill belong to the
time of Domitian (see ADONAEA, DOMUS AUGUSTIANA
), even if we reject
Hilsen's placing of the temple of APOLLO PALATINUS
(q.v.) on the site.
Nor is there any proof that the temple was in Rome.
