Signature: Drawn and engraved by the Architect Piranesi. Additional key: A On the ruined cornice of the door, marked in the aforementioned figure with the letter A, one reads the inscription below: Nicholas, whose house this is, was not ignorant of the fact that the glory of the world doesn’t have any value in itself. Vanity did not motivate him to build this house, but rather he built it to restore the ancient splendor of Rome. In beautiful houses, remember the tombs and be sure that you will not be there for long, death comes with wings and life is eternal for no one, our journey is brief and its course fleeting. Even if you flee the wind, if you close a hundred doors, or command a thousand guards, you will not lie down to rest without death. Even if you close yourself in a castle as high as the stars, death can take whomever she wants. This sublime house reaches the stars, whose culmination, the great Nicholas, first among the firsts, built from the foundations to renew the grandeur of his parents, Crescenzio, his father, and Theodora his mother. The father constructed this illustrious building dedicated to his beloved son David. B. On the curved architrave of one of the windows, marked in the same figure with letter B, one reads: I am here as the honor of the great Roman people (from the Volume I Map Index, no. 164).
