Beyond the Temple of Castor, to the right of the Temple of Vesta, are
remains of these stairs.
"Augustus lived at first near the Roman Forum, above the Ringmaker's
Stairs, in a house which had once been occupied by Calvus the orator"
(Suetonius, "Augustus," lxxii.). Calvus the orator, a friend of
Cicero, lived on the Palatine; and the Scalæ Annulariæ was a flight of
stairs that led from the east end of the Forum up the north side of
the Palatine to the Clivus Victoriæ.
On the 12th of April 1882, a piece of the marble plan was found here
which, curiously enough, represents this part of the Forum, showing
the side of the Temple of Castor and the Ringmaker's Stairs.
