On the left_ is the Tolonia Palace, and _on the right_ the Venetian Palace (now the Austrian Embassy), a building of the middle ages. _On the right-hand side of the narrow street, in a line with the Corso, Via Morforio, is the_ TOMB OF ATTIA CLAUDIA, converted into a house, the lower part being shops. By descending into the vault, it will be seen that it is hewn out of the natural rock. The Claudii family "received, from the state, lands beyond the Anio for their followers, and a burying-place for themselves near the Capitol" (Suetonius, "Claudius," i. 1). Adjoining is the house where Giulio Romano was born. _A few steps beyond, on the left-hand side of the same street, is the_ TOMB OF BIBULUS. The inscription records the virtue and public honour of a Roman magistrate of the time of the republic. It is supposed to be two thousand years old. C. PUBLICO . L. Q. F. BIBULO . AED . PL.

Giuseppe dei Falegnami. It is built over part of_ THE MAMERTINE PRISON, erected, according to Livy (i. 33) by Ancus Martius. "In order to suppress the terror, the boldness which the vicious assumed from hence (A.U.C. 121),[1] and which gained ground continually, a prison was built in the middle of the city, adjoining the Forum." Servius Tullius added a lower cell, called the TULLIANUM, 6½ feet high and 19 feet by 9. Prisoners who were condemned to be strangled or to die of hunger were thrust down the aperture; hence the phrase, "to cast into prison." Sallust ("Catiline," lv.) thus describes it:--
