Immediately after having passed under the Arch of Hadrian, one of the first important monuments met on the left side, is the
temple of the Sun
that may have been erected in 275 by the
Emperor Aurelian after his victory
over queen Zenobia, the queen of Palmyra. Its two semicircular ends make
it a quite peculiar temple. “the god of the Sun of Emesis left his sanctuary
to give Rome the victory” Aurelian would have declared. With Baal,
oriental god purified by the Greek culture, Aurelian created the god of the Romans.
This was the only attempt of pagan monotheism.
This temple was famous for its richness and its treasures.
A huge portico, the
portico of the Sun, was linked to the temple.
