Also referred to as Arch of Tiberius or
Caligula or Augustus [Gell], Arch of C. Caesar Augustus and castellum aquae [Fiorelli], Arch
of Nero [Mau], Arch of Mercurio [after street location],
According to Katherine E Welch, the statue on
which the naming after Caligula is based is probably Marcus Tullius who donated
the adjacent Temple of Fortuna.

Arch of Caligula. May 2010. Looking north from arch at the
start of the Via Mercurio.
A bronze equestrian statue was found in pieces beneath the arch.
This was (arbitrarily) identified as being Caligula and may have come from the
top of the arch.
Now in Naples Archaeological Museum. Inventory number 5635.
According to Welch, the statue wears a toga and senatorial
sandals and is realistically portrayed as middle aged.
She suggests it is more likely to be a high ranking civic
person.
She suggests that it may be Marcus Tullius who was tribunus militum a populus a non military but equestrian rank.
He was also the donor of the adjacent Temple of Fortuna
Augustus in the Augustan period.
