In the middle of the left wall there is the the original Roman sarcophagus that belonged to the ancient monument of the Saint. The surmounted recumbent statue was carved by Isaia da Pisa in 1455. The frescos on the side are by Pietro Gagliardi from the middle of the 19th century.

On the pillar to the left are the epitaph and portrait of Augustine A. Giorgi O. S. A., a celebrated Philologer, the restorer of the Tibetian alphabet, who died in 1797.
