Eleven Corinthian columns, which formed a part of one side of the
temple, still stand, forming the entrance into a building once used as
a custom-house. They are 42½ feet high and 4½ feet in diameter,
supporting an architrave of marble which has been recently restored.
In the interior are some immense blocks of marble which formed part of
the vaulting. The temple, with the Portico of the Argonauts which
surrounded it, was erected by Agrippa. It is now used as a chamber of
commerce.

_Continuing our ramble along the Corso, on the right_ is the PALAZZO
SIMONETTI, on the left the PALAZZO SCIARRA. The pictures here have not
been shown to the public for some years. Beyond, _standing back_, is
the CHURCH OF S. MARCELLO, containing the celebrated cherubs of
Pierino del Vaga, the most exquisite things ever done in fresco. The
tomb of Cardinal Weld is also here.
Rienzi's body was hung up by the feet for two days in front of this
church.
