Speculum Romanae Magnificentiae: Innenraum, zeigt eine unterirdische Kammer, die durch zwei Treppen erreicht wird, eine auf jeder Seite; Nischen auf der oberen Etage.

The Speculum Romanae Magnificentiae is a collection of engravings of Rome and Roman antiquities, the core of which consists of prints published by Antonio Lafreri and gathered under a title page he printed in the mid-1570's. Copies of the Speculum vary greatly in the number of prints, and individual prints were reissued and changed over time.
